You can’t miss this one, it is at the end of the level. These points will let you upgrade your max HP, armor and how much ammo you can hold. Depending on how you are playing, these points could be the difference between life and death.

While going through the Foundry you will come across a locked yellow door that you need to open. It is here on the map. Go down the steps and follow that path to the end of the area for a Argent Cell location. Only one in this level.

You can find this cell while you are looking to disable the Argent Filters. When you get to the area with the big blue force field, go inside the building near there and go to the bottom floor. Here, behind machinery you will find the Cell.

Shortly after you begin the Argent Energy Tower level you find some boots that let you double jump. You need to head to the far end of the main room and jump up some ledges to reach a secret. The image above is the platform you need to reach, the secret is just to the right in a small area you can drop into.

There’s another cell on this mission. Towards the end of the Argent Energy Tower mission you’ll reach a room with a large red beam coming down the middle. There’s a big fight here with some new enemies. Once you finish them off you have to go through a door to use a computer to progress. Before you use the computer walk past it and down the hall to find another Argent Cell.

You can see this one in the large area with the red pool of blood in the middle and huge amounts of enemies. Don’t fret, you can’t get it straight away. Progress through until you find the Blue Skull Key. Use that to open the Blue Skull door and the Argent Cell is inside.

You won’t be able to find this one until right near the end of the level. You can see the Argent Cell from a nearby ammunition box. As you reach the station you’ll see a platform with enemies, a hive and a spaceship. Before taking out the enemies and finishing the level turn around and jump onto a large group of rocks just off the edge. The Argent Cell is there.

Impossible to miss the first one. It’s inside the room you enter to use the terminal straight after you kill the fat enemy demon.

The second cell is a little later in the level, after you go through the first airlock. After you clear the area outside the airlock and remove the blue field, jump the gap to the other side like you are going to progress. Look down and to the left to see a path going up a way. Jump down to that path and follow it to the cell.

This one is pretty hard to miss. When you bring down the Helix Containment Field, look to the right and you should see the Argent Cell.

The first one is easy to find. Continue through the mission until you’re just about to go through the Yellow Door. Before doing so, make sure to check the door to your right. Inside that room is an Argent Cell.

Go through the first green portal at the start of the level. In the next room is one of the Slayer Testaments that you have to interact with. Just nearby is an Argent Cell for this level.

Doom Praetor Suit Upgrade 1 – You can find your first suit upgrade in The UAC level. After you open the door with the blue keycard for the first time, go down and stick to the right. You will find a small cave that you can enter. Kill the enemies inside and grab the automap.

You can walk right past this one if you aren’t paying attention. When you go to restore the power to the Maintenance Door you can find the Automap in the hall.

Progress through the level. When you reach the Plasma Rifle you’ll enter a room with a few crates and some robotic arms. The next room has some lava being poured into the middle. Follow the stairs all the way up and you’ll see a door on your right. Ignore that and take a left, the Automap can be found at the end of the walkway

The Automap for the next mission can be found inside the large room with blue lights and electricity surging through various spots. On the bottom level in the far right corner of the room there’s a large door. You can’t interact with this door but there’s another smaller door to the right, you can pry it open and explore inside to find the Automap.

Progress through the level until you reach the short cut-scene with Olivia running away with some Argent Energy. Head around to the left to enter the room through the door. The Automap can be found in the back right corner.

The Automap in Kadingir Sanctum is a bit deep in the level. You can find it right after you open the second red skull door. Follow the stairs down and skip past the teleporter to the next cave. The Automap is in that cave, it looks a little different though.

Continue through the mission until you enter the complex where you meet a new type of enemy. The mutant dog type things that charge you. Inside this room walk into the middle and check to the right, the Automap is directly ahead.

Once you get off the tram and defeat the large demon enemy, take a left and you’ll see two entrances. One to a male toilet and the other to a female. Head into the ladies room and look up, there’s a vent in the ceiling. Jump off the sink area and grab on. Follow it through to find the secret area and the Automap.

This one is close to where you run into the Weapon Mod bot. When you are going through the computer consoles you can find a vent on the wall. Follow that vent down to the area below and you can find the Automap down there.

Titan’s Realm You will find the Automap right after you take the second green portal, can’t miss it.

Continue through until you get to the room with the Yellow Skull Key. Clear the room and the Automap will spawn in the small indent in the wall directly next to the key.

Continue through the mission until you enter a door with “Clean Area” written above. It’s after the large room with the two switches. Go through the door and then through the next door you see, you should be inside a room full of terminals and a couple of holograms. Search the left side of the room for a hatch in the floor that you can interact with. Go down the hatch, past the guy with the blue key and then into the door on the left. Automap is inside.

Doom Praetor Suit Upgrade 1 – You can find your first suit upgrade in The UAC level. After you open the door with the blue keycard for the first time, go down and stick to the right. You will find a small cave that you can enter. Kill the enemies inside and grab the automap. At the end of the path leading out you will find a dead guard with your first upgrade.

There are three in this level.

Praetor Suit Upgrade 1 – Your first upgrade for the level will come after you get the yellow key card. Go to the locked yellow door but do not go in it yet. Instead look behind you for some boxes you can climb up. Climb up and over and cross to the other side. Open the yellow door on the other side and then use the computer. This will open up a few of the other locked doors in the area.

Go into the hallway outside the room and then look right for a hatch that you can open now. Go down the hatch and you will find the upgrade.

Praetor Suit Upgrade 2 – Now that you have used the computer to open all the red locked doors, you will need to go back up the elevator to where you got the yellow key card. There will be a new open door there and inside is a vent you can go into. On the other side of the vent you will find the guard and a new secret.

Praetor Suit Upgrade 3 – The last upgrade in this level is after you are told to go to the Vegas system. On your way to the Vega computer you will have to use another computer to gain access to the doors in the area. After you do that, go through the door near the computer and follow the path left for the upgrade.

Praetor Suit Upgrade 1 – When you first enter The Foundry you’ll discover a large room area with lava pouring down the walls. Jump to the right and enter the room there. Follow that around to the outside and then drop down here to find the upgrade. If you got the hand from the dead guy, it’s right below that.

Praetor Suit Upgrade 2 – You can find this one right before you destroy the first Gore Nest in the level, you need the yellow key card to access it. Go through the area until you hit the end of the conveyor belt with the boxes on it. You have to go through the door but before you do that look right. There are some boxes you can climb up and you can use that to access a vent shaft with the upgrade in it.

Praetor Suit Upgrade 3 – Near the end of the level, after a large battle in a room you’ll get a comm message saying Olivia has activated a terminal nearby. Through the next room you’ll find another body with a Praetor token.

Praetor Suit Upgrade 1 – Keep progressing through the level until you reach a large area where you encounter the upgrade bot, although it flies away. Look to the right and you’ll see a shining weapons box. Even further down to the right is a small area a long way down. Jump down and follow it round to find another corpse with an upgrade token.

Praetor Suit Upgrade 2 – This one is in the same area as the last one but on the other side. Go to the blue force field and look up for a hanging crate. Use the creates near there to jump up onto that one and then up to the next section of building. Look right and you will see a cat walk that you can get up on. Go up on the cat walk and at the end you will find the upgrade.

Praetor Suit Upgrade 3 – The next upgrade can be found really close to the second one. Look over the edge near the last upgrade and drop down. Look left and then jump up on that rock and look down from the edge of that. You will see a path down below, follow that to the upgrade.

Praetor Suit Upgrade 4 – The last upgrade will come towards the end of the level. When you destroy the last demon spawning thing and clear the wave, you will open a door that leads to the Argent Processor. Look left in that room and you will see the dead guard.

Praetor Suit Upgrade 1 – When you reach the end of the bridge in the Argent Energy Tower mission and jump across the gap, drop down to the right and you’ll find a secret area.

Praetor Suit Upgrade 2 – Continue through the level until you reach the area with the large metallic containers rotating around a circular structure. You have to drop down to continue. As you progress take the first opportunity to jump to a left ledge. You can find another Praetor Token there.

Praetor Suit Upgrade 3 – Towards the end of the mission you have to climb the huge tower. Just before you enter the room where you hear Olivia and your objective updates. When you get near to the top there is a section where you can jump past some moving metal containers back into the main room for Rune Trial, but don’t jump all the way out. When you jump onto the ledge turn back and wait for a container to come back around. Jump onto the container and then onto the ledge opposite. There’s an ammo box here. From the ammo box jump up to the left to a higher ledge and then turn back on yourself to jump up and find another Praetor Token.

Praetor Suit Upgrade 1 – Continue through the mission until you get the Yellow Skull key and unlock the Yellow Skull door. Inside is a dead Elite Guard with another Praetor Token to collect.

Praetor Suit Upgrade 2 – After you unlock the Blue Skull Door and go through the teleporation device you will come to a huge area with floating rocks and lots of enemies. Directly across from where you enter the area you’ll see an armor pickup on one of the floating islands. Past that further is a platform with some stairs. Climb those up to the top level and search nearby for the dead Elite Guard.

Praetor Suit Upgrade 3 – Another tough one to miss. Continue through the mission until you reach the yellow teleportation device. You should spot the Elite Guard just before.

Praetor Suit Upgrade 4 – This one is also near impossible to miss. Continue through the level, just past the point where you interact with the Slayer’s Testament III. Follow the path round to the next area, jump across and you’ll see the Elite Guard there.

Praetor Suit Upgrade 1 – Continue through the level for a few minutes. Eventually you will drop down into a destroyed corridor covered in flames. When you drop down a door is ahead but before entering turn around and you’ll see a dead Elite Guard with a Praetor Token.

Praetor Suit Upgrade 2 – In the main area there is a Rune Trial. If you look over the edge of the Rune Trial location there’s a small ledge with fire on it. Jump down there and then turn to look at the area below the Rune Trial. There’s a very small ledge with a Praetor Token inside. I was only able to jump onto the ledge from above using the In-Flight Mobility Rune.

Praetor Suit Upgrade 3 – Carry on with the mission until you reach an area filled with enemies and 2 blue jump pads on either side. Jump up and you’ll find the corpse of a Elite Guard nearby.

Praetor Suit Upgrade 4 – Right at the end of the mission you jump down an elevator shaft. Before turning to go to your objective look above you and jump into the small gap. Explore inside for another Praetor Token.

Praetor Suit Upgrade 1 – Once you get off the tram and defeat the large demon enemy, take a left and you’ll see two entrances. One to a male toilet and the other to a female. Head into the ladies room and look up, there’s a vent in the ceiling. Jump off the sink area and grab on. Follow it through to find the secret area.

Praetor Suit Upgrade 2 – After you meet with Samuel Hayden inside his office he tells you to use the service elevator. Head down to the bottom and take your first left. The Elite Guard corpse can be found near some crates.

Praetor Suit Upgrade 3 – As you go through the level you will eventually come to a point where a giant fan pushes you up to the ceiling. Go through the vent at the top and follow it to the end. At the end, go through the left door and inside you will find your upgrade.

Praetor Suit Upgrade 1 – The upgrade can be found after you kill the first demon spawn thing. Go through the door until you get to what looks like a dead end. Jump up to the ledge that leads to a maintenance door but don’t go through it. Instead, look behind you and jump over to the other vent. At the end of that path you will find the armor upgrade.

Praetor Suit Upgrade 2 – The second upgrade can be found after the room with the giant demon being operated on. If you go to the area outside where it is being operated on you can see a slant that leads up to a closed door. There is a switch you can hit near the door to open it and inside is the upgrade.

Praetor Suit Upgrade 3 – As you move through the mission you will eventually reveal a hidden staircase that you have to go down. Follow the path until you get to a room with a hole in the middle. Jump in and you will get the secret and an armor upgrade.

Praetor Suit Upgrade 4 – The last Praetor Upgrade in the level is right after you close the portal. Go through the next door and take a right into the large room with the vending machines. If you look to the right of the vending machines you will see an opening on the wall. Go in there and you will get your last upgrade.

Praetor Suit Upgrade 1 – This one is pretty early in the level. As you progress you will enter a large room with a toxic floor that you are above. Clear the room and then drop down under the bridge into the toxic goop. Under the bridge you can find a skull switch to hit. This will open up a door on the right side in the toxic goop, your upgrade is inside.

Praetor Suit Upgrade 2 – Continue through the level until you reach the area with the Yellow Door. When you drop down the door is sealed and you have to go down to the left into another area filled with green goo. There’s a switch at the far end of the room you need to press, the Elite Guard is next to the switch.

Praetor Suit Upgrade 1 – Keep progressing through the level. When you activate both the switches behind the blue and yellow door you’ll have to drop far down below. Keep going and enter the door with the large skull above it, the marine corpse can be found inside.

Praetor Suit Upgrade 2 – Carry on through the level and eventually you’ll reach a large corridor type space, filled with ammo and pickups. There’s a ton of demons that spawn in here but after you clear them out check the end of the corridor for the Praetor Token. It’s in an area you have to progress through so you can’t really miss it.

Praetor Suit Upgrade 1 – Right near the beginning of the mission. Proceed through the doors until you get outside in the snow. Before jumping up the first platform, check to the right for a Praetor Token.

Praetor Suit Upgrade 2 – Another easy one to find. Continue through the mission until you enter a door with “Clean Area” written above. It’s after the large room with the two switches. Go through the door and then through the next door you see, you should be inside a room full of terminals and a couple of holograms. Search the left side of the room for a hatch in the floor that you can interact with. Go down the hatch, past the guy with the blue key and then into the door on the left. The token is in the next room.

Praetor Suit Upgrade 3 – Continue through the mission until you have to jump on the tram to get to the next area. When you get there clear out all the enemies. To move forward you need to stand on a lift that will take you up to your objective but before getting on the lift, check around to the side and drop down underneath it. There’s a secret here and a Praetor Token.

This will be your first weapon mod to find. While you are in The UAC level you will have to use a blue key card for the first time. When you go through that door, follow the path below down until you hit a broken bridge. Run and jump across the bridge then look right to see your weapon mod.

Charged burst takes about a second to charge and shoots three shotgun blasts in a row rapidly. This doesn’t have a cool down and you can keep using it as long as you have 3 shotgun shells to spare.

The explosive shot mod shoots an explosive shot. It has a bit of a cool down on it so you can’t spam it. You can normally get one-off every 5 seconds or so without any upgrades.

You will get both eventually but for now you have to pick one.

You will find the second Weapon Mod in the Resource Operations level. The robot is right by the yellow key card that you have to find. Now you will get the mod upgrade you didn’t get last time.

This one is pretty hard to miss but here’s a picture on of where it is on the map.

When you spawn in just follow the path out to the main part of the foundry. Go right and jump across to the door on the other side. Inside you will find the bot and some other supplies. I went with the missiles on my heavy assault rifle for some extra bang.

Field Drone 1 – You actually see this one pretty early but it runs away when you find it. When you get to the first demon spawning thing then you are close. Clear the area and then look down below. Go around the force field and you will see a path that leads down into a jammed oor. Duck under the door and you can find the bot and supplies there.

Field Drone 2 – You cant find this mod AFTER you close all the filters. Start heading towards the Argent Processor until you run into a fork in the road. Look left fora crate that you can climb up and do so. Jump the gap to the left and follow that path to a building. Inside you will find some enemies and a mod robot.

Field Drone 3 –

Field Drone 4 –

Field Drone 1 – As you reach the area where you have to cross the bridge stick to the left side. A short distance across you’ll see several sets of stairs that lead up to higher levels. Follow it all the way up into a room. From there cross the bridge into another room. This is the secret area with a Combat Support Drone.

Field Drone 1 – Impossible to miss this one. Towards the end of the mission after you use the yellow jump device.

Field Drone 1 – This is in the room where you move the crane out of the electrified water. Jump onto the crane and then jump to the right. Follow that around and you will get a weapon mod and the secret.

Field Drone 1 – Keep progressing through the level and you will eventually come to a fan that will blow you up to the ceiling if you go on it. Go around to the left and deactivate the fan and drop down. Drop below the fan and go through the vent to find a weapon mod bot.

Field Drone 1 -Can’t really miss this one. Once you get through the Maintenance Door you will find the robot, it’s on the path you have to take.

Field Drone 1 – Continue through the level until you reach the room with the toxic liquid on the floor. From there head into the next area, take a right and then a left and follow the path to the end room. You’ll see a red symbol on the back wall of the room so you know you’re in the right one. At the top of the small stairs when you enter there’s a hidden switch, it’s on the left as you walk towards the room. Clear out the demons and the switch opens. Hit it and then walk back towards the way you came in but take a left, the wall is now open. Head inside for the Field Drone.

strong>Field Drone 1 – Continue through the level until you activate both switches behind the yellow and blues doors. You’ll then have to drop down a huge hole. Continue forward through the door with the large skull above it, in the next area you’ll see the drone on the left hand side atop some stairs.

Doom Weapon Upgrade Point 1 – You can find this weapon upgrade point right after you use the blue keycard for the first time. When you open the door and go through, stay to the left until you get to a metal building. Enter the building and drop down all the way to the bottom and turn around. You are looking for a door way that you can enter with a switch inside.

It is not the white open door one the left, it is the doorway on the metal part in front of the Doom guy. The white door is what you open when you hit the switch inside. After you hit the switch, go into the room and clear out the enemies for an upgrade point. You can also hit the 2 red switch on the shelf to get a secret inside the secret.

Doom Weapon Upgrade Point 2 – You need to collect the secrets in a level to get a Weapon Upgrade Point as well. We have a secret location guide here.

Now you start to get challenges that unlock points as well.

The first challenge is the only tricky one. All you have to do is make two of them flash and then get both of them in your shotgun cross hair to finish them. I hit them both in the chest and they exploded. You might be able to use grenade if you go the explosive mod, but I wasn’t able to test it.

Our secret guide can be found here.

The trick one here is getting the aerial glory kills (death form above). You have to be on a ledge or crate above the enemy when the glow and then do the glory kill. I would wait until it was one on one and then lure them to the crates and do the kill. It does take some time because the AI does NOT like to run directly at you.

Our secret guide can be found here for the collectibles.

You need to get two Death From Above kills on Hell Knights this time. They are the really large brutish demons. Stun them, look for a way to get above them, jump at them and smash there heads in! You will fight enough in the level to get 2 easily. The map can be found in our secrets guide.

Our secret guide can be found here for the collectibles.

The difficult one here is the Kill 15 demons with Quad Damage. I was able to find two of those buffs in this level and both where during waves of enemies. Check for them while you are fighting at the base of the tower and while you are climbing it.

Our secret guide can be found here for the collectibles.

First weapon you get and you can’t miss it. As soon as you spawn in you have the gun.

You can’t miss this gun either. Just keep walking in the first area and you will pick up the shotgun.

You will find the Frag grenades after you open the first locked blue door. These will really pack a punch. Grenades in this game have a cool down, you don’t have to find any extras but you can’t spam them either.

The Chainsaw can be found in the Resource Operations. Eventually you will come to a room that says “To many demons going into lockdown mode”. After you clear the demons you will enter a locker room and the chainsaw is on the corpse in there.

The first truly hidden weapon. During Resource Operations you will run into a locked door that takes a yellow key card. Go to the locked yellow door but do not go in it yet. Instead look behind you for some boxes you can climb up. Climb up and over and cross to the other side. Open the yellow door on the other side and then use the computer. This will open up a few of the other locked doors in the area.

Go into the hallway outside the room and then look right for a hatch that you can open now. Go down the hatch and then go up the other hatch on the other side. Go near the blood smear on the wall up there to find the Plasma Rifle.

The Heavy Assault Rifle can be found on Resource Operations. After you open the door with the yellow key card, look left for a room. Inside that room you will find the machine gun.

During the Argent Facility mission where you have to disable the Argent Tower filters. Keep moving forward until you reach a room with bloodied corpses hanging from the ceiling directly above a strange pentagram style symbol. The nearby body of a marine has the Rocket Launcher

This can be found on the Argent Facility mission where you disable the Argent Tower filters. Progress through the mission until you reach a large blue room with electricity surging in locations. You’ll have to fight a mini-boss in here. When you’ve killed it head to the next area. As soon as you exit the door check to your right. There’s a broken area in the railings. Drop down there and walk around to discover the Super Shotgun on a corpse.

Towards the end of the Argent Energy Tower mission. When you reach the room just before the end with the huge elevator shaft, after climbing the entire way up the tower. There’s a Plasma Rifle, the Hologram can be found on the storage box just next to the Plasma Rifle.

After taking the robot lift up to the tower you will end up in a room with a locked lift in it. You can’t do anything from here, but behind that glass is where you want to go. Follow the path out like you are just progressing and jump past the moving energy containers out towards the tower. Instead of dropping down, turn around and jump across. Go forward a bit until you can jump again to the left and do that. Keep going until you are on a path that leads up some stairs. Up here you can see the lift is opened and you can drop down below. Look down before you jump because the landing can be a bit rough, use the double jump if you need to..

During Kadingir Sanctum right after going through the red three skulled door you will take a teleporter. This teleporter will lead to an area with some supplies before a pretty big fight. If you walk to the edge after the hallway and look down you will see a power up and a path going left. Take the path going left and you will get a secret and a Chaingun early

You can find the BFG in Lazarus Labs. The BFG cannot be missed but there is a little puzzle attached to it. When the laser trap is above you, look around for red lights under the laser grid. Shoot a few of those and this will free the BFG.

You can find this grenade during the Titan’s Realm Mission. I actually didn’t even realize it was a weapon until I walked over it, it can easily be missed. During the mission you will eventually have to pass through something called the Titan’s Core(a green teleporter that is blocked until you clear the room). In this room you can find the grenade on the ground, in a corner behind the warp bubble. These regen some of your HP when you hit demons with it.

The UAC has three secrets to find.

Doom The UAC Secret 1 – The first secret you will find is right after you get the blue key card. Jump up on the crate near the key card and look up to see a green light near a ledge. Jump up to the ledge and grab the collectible for a secret.

Doom The UAC Secret 2 – The second can be found right after the blue key card door. Follow the path down and stick to the left side of the wall. Keep going until you find a metal building you can enter. Enter and go all the way to the bottom of that area and turn around. You should see this when you turn around. There is a doorway with a switch you need to hit. The switch can be located through a small metal opening below the fan, check out the picture below.

It is not the white open door one the left, it is the doorway on the metal part in front of the Doom guy. The white door is what you open when you hit the switch inside. After you hit the switch, go into the room and clear out the enemies for an upgrade point. You can also hit the 2 red switch on the shelf to get a secret inside the secret.

Doom The UAC Secret 3 – The last secret in the level isn’t actually all that hard to find. You can just crawl through the hole next to the collectible or jump across. Here is a picture of where on the map.

Doom Resource Operations Secret 1 – When you restore power to the door switch using the computer, turn around and jump up into the opening. Follow the path to the end and you will get the secret.

Doom Resource Operations Secret 2 – The second secret is when you drop down the maintenance door. Follow the path until you get to a cat walk that leads to two doors. The one on the left is the secret door we are going to open. If you look up you will see a platform above the door. Use the containers that you passed to jump up to the top. Hit the switch at the top and open the door down below. Enter for another secret.

Doom Resource Operations Secret 3/4/5 – The next secrets need you to have the yellow key card. When you have the yellow key card you need to go to the security room and use it to give you access to the area. From the yellow card door jump up the boxes and cross over. On the other side there is a room you can use the key card to enter, that is where you get access. Go outside the room and into the hallway to find a hatch. Go down the hatch and grab the armor upgrade and go out the other hatch. Here you will find the Plasma Rifle and another secret.

Doom Resource Operations Secret 5/6 – Once you have the security access you will need to use the elevator to go back up to where you got the yellow key card. The room to the right of the card will be open and inside is a secret. Follow the vent in that room and drop down on the other side for another secret.

Doom Resource Operations Secret 7 – The next secret is found after the yellow key card door, when you are outside. Near the entrance to the building you will find a single box hat has blood on it.

Climb up that box and then up further. Follow the vent up to the right and at the top look behind you. Jump to the next vent and follow that until you can jump onto the roof. On the roof in the back corner you can find the collectible. You can then use the hatch on the roof to go back down into the building if you want.

Doom Resource Operations Secret 8 – The last secret in the level is right at the end, near the Vega terminal. Instead of using the terminal look left and climb the boxes up to the top. Go through the vent and grab the collectible to get all the secrets.

After you spawn in head out to the foundry and jump the gap to the left. Follow that path until you can make a right towards a cart on a platform. Jump onto the platform and pull the lever on there to unlock the Retro Doom Level. It is across the bridge near the pouring lava – Thanks for the help vipLink.

Doom The Foundry Secret 1 – When you reach the room shown in the screenshot above head to the far side, where you see the lava pouring out from the tubes in the wall. Drop down between the 1st and 2nd tubes onto a platform, turn around and you’ll see the MarineGuy there.

Doom The Foundry Secret 2 – This secret is just for some armor but you need it for the weapon point. When you get to the computer that needs a hand to verify, go out the other door you didn’t come in at. This is another foundry part with a missing bridge. Jump to the bottom and follow the green lights for jump points back up but on the other side. When you get to the top you will get the hand. Before you jump off, go all the way to the left and jump into the vent at the end for the secret.

Doom The Foundry Secret 3 – Progress through the level and eventually you’ll grab a Plasma Rifle before heading into a room filled with enemies. On the right side of the room there is a group of crates with robotic arms. Search inside the middle crate for a MarineGuy

Doom The Foundry Secret 4 – This one is in the same room at the second Marine guy. Before you go into the next room, look right and you can see some crates to climb up. Jump to the vent across and you will find a secret and an armor upgrade!

Doom The Foundry Secret 6 – Last secret in the Foundry is in here 😉 You need to jump on the pipes marked with 1, and then jump to the other side and there’s the corridor. Rocket launcher in there. Huge thanks to Kamil Bar for the information and screenshot.

Doom Argent Facility Secret 1 – This is the Doom Retro room for the level. As you are progressing through the level you will enter a hall with lots of blood, gore and demonic symbols. Go back out the door oyu can in and go to the right. Around the corner you will find some supplies and the lever for the retro level is there, behind some barrels.

Doom Argent Facility Secret 2 – You can find the first secret while you are shutting down the Argent Filters. When you get the blue force field, go into the building near there and look to your right. You will see two boxes tacked on top of each other. Jump up on them and then jump higher to get the MarineGuy.

Doom Argent Facility Secret 3 – This one can be found when you are going after the last Argent Filter. There is a haste buff in this room also to help you know what room I am talking about. Go to the bottom of the big room with the blue light and you can find a broken door you can force open. Force it open for the secret and the Automap.
