Doom Secret Locations Guide

[line style=’solid’ top=’10’ bottom=’10’ width=’100%’ height=’1′ color=’blue’] [accordion initial=’1′] [accordion_item title=’The UAC Secrets & MarineGuy Locations’]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.

Doom Weapon Upgrade 2

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.

[/accordion_item] [accordion_item title=’Resource Operations Secrets & MarineGuy Locations’]

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.

[/accordion_item] [accordion_item title=’The Foundry Secrets & MarineGuy Locations’]  Foundry Missing Secret
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 Foundry Secret 1
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 Argent Energy Tower Secret 1 – 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.

Doom Argent Energy Tower Secret 2 – As you reach the area where you have to cross the bridge stick to the left side.

Doom Argent Energy Tower Secret 6
Doom Argent Energy Tower Secret 6 – After you climb the Tower for a bit you will have to fight another Demon army. After you kill them you will need to use the computer to activate the lift machine. There’s a green one right outside the computer room but oyu don’t want that one. Instead go to the other side and use the white light one. Let it take you to the top and activate the switch up there to unlock the Retro Doom room for the level. Take the robot back down, wait for it to lift off again and enter the room.

Kadingir Sanctum Secret 1 – Progress through the mission until you reach the area with the large green pool of liquid. From there go up the stairs and you will see a flashing green beacon at the top. Turn directly to your left and climb some rocks. You will see a nearby armor pickup further up some more rocks. Climb to get this secret.

Kadingir Sanctum Secret 2 – You can see this secret to the right after the first door but you can’t get there until later. Progress through the level and eventually you’ll loop back around to the starting area but now there will be some floating rocks up to a platform with a skull switch. Click the switch to open the huge door near the beginning of the game.

Kadingir Sanctum Secret 3

Kadingir Sanctum Secret 3 – You can find this one near the blue door, you can’t access it until you can open the blue door though.

Now you should be able to see a small floating platform you can jump to, do that and then follow the path up to get

Kadingir Sanctum Secret 5 – This secret unlocks a special Doom Classic level. Continue through the mission until you reach the area with the massive fight. Minotaur style enemies, witch type things, eyeballs, the works. There’s a huge door nearby with a green icon on it. Don’t go there yet. Near where most of the enemies spawn is a cave. Inside the cave there’s a lever, pull that. There’s also a Skyrim Easter Egg nearby for fans of The Elder Scrolls. After pulling the lever head out the cave and to the right. Jump down to wear you see the armor pickup and you can see the cave into old school Doom near the blood pools.

Once at the top follow the walkway around until you see a platform with a column on it, there’s a big 1 written on the column. Drop down to the left of that and explore the gap in the rock, there’s a MarineGuy there and a secret area.

Argent Facility (Destroyed) Hell On Mars Secret 2 – At the start of the level go outside and follow the cat walk up until you run into the demon with the big eyeball. Kill it and then look to your right and jump up the machines there. Now look right and keep jumping up until you end up on another cat walk and follow it.

Instead of going into the pipe down below, to to the upper right and follow that up. There are two secrets here, jump into the little cave where the pipes are leading for a MarineGuy. Now this second is a switch that you can see through the fence next to those pipes you used to find the MarineGuy. There is a platform you can jump up to to the left that goes up pretty high. Once you get to the top, look back towards the pipes for the switch you need to go hit. You will need to double jump to make it and even then it will be close. After you hit the switch, go back to the airlock area and the Doom retro level is there.

Johnny Hurricane's Gamer Biography


  1. “There is VERY clearly another section of the map that I could not figure out how to get to”

    In the center of the map is a walkway/bridge that connects that part of the map to the Vent entrance (mission objective). There’s a mine Cart with a lever to the right. aktivate it and the section opens up… still missing one secret on that level thought…

      1. one of the secrets in the foundry is finding a rocket launcher, it doesnt have anything to do with that door. on the left side of the map, after you finish the gore nest up against the wall thats surrounded by all the broken bridges with a lake of lava underneath, if you stand where the gore nest was theres a door up to the right, normally you navigate through it back to the main area, but if you explore it a bit you end up in a room with a rocket launcher, and that triggered my last secret for the foundry

  2. On Argent Energy Tower: At the point you shoot the elevator brakes if you look down there will be a platform you can double jump on while you drop down. this will give you a guass rifle, as well as the last secret (assuming you have done all others on the way)

  3. The 5th secret is the classic map area. Right near the start of the map there is a lever you pull which opens the door. Took me forever to find. It’s right before the corridor with the Red symbols on the floor, hidden behind some barrels.

  4. Kadingir Sanctum: After using the blue door key. You approach an area where 3 blue skulls fly by. In that area on the lower level, if you keep going straight and around the bend. You will find a secret Minigun

  5. I found another one in the foundry. After the third gore nest on the lower level head back through the skinny door that led there. Follow that short hallway back to the fork that has you staring at the big fan inside the wall, make a left then another left and stand facing the small staircase and look up, there’s a room there, you’ll have to crouch to get into it.

  6. And I found the classic room in the foundry as well. Second bridge you cross on the top floor, look to the left, there is a lever that open the door to the area that seem impossible to get to.

  7. 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.

  8. There’s another secret you missed in the Argent Facility level, it’s just past the last marineguy but instead of going through the big door towards the argent energy, go down the little path left for a secret and a super shotgun

  9. Hey Bud I’m stuck on Doom Resource Operations Secret 7. I’m right outside the entrance of the airlock door and I can’t find the box with blood on it at all. I went further along and still found nothing. So before I move into the Vega part I want to get this secret. Can you please offer some guidance? Thank you!

  10. Another on in Kardinir Keep is in the bit where there’s a bunch of Mancubus’ and an invincibilty powerup, go to the left along the cliff and after a hell knight there’s a chaingun and a commander keen helmet, like the skyrim one

  11. In the foundry, the part of the map he’s referring to is the hidden classic doom area. The lever to open it is on that thing sticking off the left side of the bridge as you approach it.

  12. I found this in titans realm. Its not a secret for the game but it is a cool find. its in the room after using the first teleporter. Far top right. its a fake wall and you will have to jump to get to it.

  13. On Lazarus Labs, what do ppl find best to get the 10 demons one shot challenge? I tried the BFG 9000 but I’m not sure that works (maybe I was just under 10). Any opinions?

  14. I’m trying to find the two boxes that you’re referring for the first secret on Argent. I go to the room nearest to the blue force field and don’t see anything. Any additional help on this one?

    1. You have to keep going until you get to the room which activates a cargo bot that goes through the stuck hatch. It will then drop the second box. This drove me crazy.

      1. Nice! I’ll try that now, thanks a lot bro. I’ve been streaming on twitch to try and get help too lol.

      2. Okay I’m standing above the opening where the lift is stuck with the two boxes on it. I didn’t see any marine guy

  15. In the Foundry, the large secret area on the side of the map opposite the cooling turbines can be accessed by going to the large middle bridge, hopping up on the square block next to it, and then going to the right-hand side where a lever can be pulled. That opens a door in the wall to access the secret classic level.

  16. question, does anyone know if I can go back to areas if I missed a secret location? I missed the plasma rifle… T_T

    1. Well I found out if you pick up the plasma rifle anywhere other than the secret area location you have to start that whole save over because you can’t get it sonce the gun it self is considered the secret.

      1. So I can’t go back to get it and I can’t pick it up either. Well guess I’ll restart…

        1. The gun is like a ammo drop, if somehow you don`t get the secret by going near it(guess outside the PS4 its an issue), just use the gun to waste some ammo and pick up.

  17. Last Secret in Argent Energy Tower Is in LIFT SHAFT, when you climb to the top and you need to destroy lift safety locks, look down into the shaft, you will see a shelf hidden one floor below, just go there and use second jump (from double jump boots) to lose the tempo, and you will get a nice prize which is Tesla Canon

    1. I haven’t tested that secret without the plasma rifle, but I know you can pick up guns for their ammo if you’re not full.

  18. Superb guides, cheers Mr Hurricane and all contributors, despite my best efforts some of the secrets were reaching Tomb Raider 3 levels of ‘where the…?’, but no longer. Absolutely loving the game 🙂

  19. Argent Tower Secret 7:
    Near the top of the tower you will come to a lift shaft. This will queue Olivia to squabble about something she’s owed. Instead of jumping across, look down and you will see a small opening. Jump down to it and claim the gauss cannon.

  20. Kadingir Sanctum Secret 6: (in between 3 and 4)
    Past the blue door you will see three lost souls fly by the opening to the next area. Defeat the two mancubi and the accompanying riffraff. Below there is an invulnerability powerup. Follow the path left of it to spawn a hell knight. Once properly brutalized, go to where he spawned and look left for a secret chaingun.

  21. The last secret in the Necropolis is an easter egg of Doom II. Juste before the last arena you will find a giant skull with a red mark. Shoot the mark with a rocket (I didn’t try something else) and it will drop a skull’s cube with a doomguy Inside.

  22. Last secret in Necropolis is towards the end of the mission. You’ll step into an area where there’s a group of monsters infighting. In the distance, towering and unmissable, is an enormous goat skull. Directly in the center of its forehead is a rune, and, in an homage to the DOOM II boss Icon of Sin, you have to fire a rocket into that rune. A box with classic skull textures will slowly descend and land, revealing the last MarineGuy and the last secret.

    1. Didnt see you had posted. Should have looked lol. Glad to know I wasn’t wrong on it tho. Lol 🙂

  23. There is a secret Doom level on the Foundry as well. There is an area with some lava in the middle, you can either walk around the right against the wall or jump across the lava. There are also some green tubes coming out of the wall. In the corner, there is an explosive barrel. Shoot it to open the door that previously wasn’t there.

  24. In the Argent energy tower miscion the last secret area is located at the elevator shafts you jump up. If you look down the shafts you will see an opening. Fall down and jump at the right time to catch the ledge and you will find the gauss cannon there.

  25. In Argent tower there is one more secret. When you have to shoot the supports for the elevator jump into the shaft after it falls. If your looking down you’ll see a platform. Time your double jump to catch that platform and pick up a new weapon.

  26. I found the third secret in The Necropolis.

    After collecting the second Doomguy figurine, progress until you hear the demon lord speak. You’ll see a giant skull with glowing markings on its head. This is a reference to the final boss in the first 2 Doom games. Shoot it with a rocket and you’ll get the third Doomguy figurine.

    There are youtube videos on this as well, so check those out.

  27. The last secret for the necropolis is towards the end of the level. As soon as you jump the floating platforms and proceed into the last area and fight off both waves of enemies you will see a giant goat head above the last door and two cacodemons will spawn, kill them then shoot a rocket into the glowing part of the skull and a box will appear and you will get a marineguy

  28. The final secret in the Necopolis is obtained in the first open area after jumping through the hole below the yellow and blue skull doors. There is a large goat head on the wall with a rune symbol in its forehead, Shoot the symbol with a rocket, and it will proceed to shoot a cube with skulls on it (the same way it did in the final level in Doom II) toward the next part of the map. Follow where it lands and it it blows open a rock section to reveal the final Marineguy and secret for the level.

  29. Secret 5 in the Foundry is the classic doom level. Find the lever switch next to a large box that will require you to jump off of a bridge to reach it (see first picture). The location for this is the on the map in picture 2. This opens up the HUGE doom level nearby, the location should be pretty obvious (my character arrow on the map is pointing towards it). See the map in picture 3 for the location of the entrance. This is the largest classic Doom level I have found so far, and I think it may be the only one that also plays classic Doom music. It is full of demons, health, ammo, armor, etc.


  30. Advanced Research Complex Secret 4/5

    You can crouch jump onto the pipes in the tunnel with the Marine Guy then walk out and drop down to the switch. You can do the same to get back into the tunnel.

  31. VEGA Central Processing Secrets 2

    The Elite Guard leaning on the boxes with the lever (Secret 3) you need the blue key to access is Secret 2 not the automap.

  32. On necropolis… I think the other secret is… Before the boss fight you fight two barons in front of a giant skull, on the forehead is a glowing symbol, shoot it with a rocket…
    Not positive if this is it.. But it’s what we’ve found.

  33. Last secret on argent energy tower is : In the room where Olivia’s comm talked about what she promised/ owed, do not jump yet across the room under broken elevator with 4 elevator breaks. Instead shoot 4 elevator breaks from crates room. After the elevator falls, go jump down and you will find small room. You will be given Gauss cannon. The same location will also provide Emergency button to open the nearest elevator door to go back up. The location is shown on image uploaded.
