Delta Labs - Level 2a: Union Aerospace Research Division
Map name: game/delta2a

Delta Labs - Level 2a: Union Aerospace Research Division is the sixteenth level of Doom 3. The player goes through the teleporter for the first time. The BFG9000 is first received. Before the cells are unlocked, the player can see some various interesting scripts for zombies doing stereotypical zombie acts, like eating a corpse, banging the head on a door, etc.


The marine continues searching for the source of the invasion. Eventually, he reaches the office hallway with three doors, one leading to Operations (labeled Sector 2), another one to Security & Bio Labs (Sector 3), and another to Teleporter Access (Sector 4). The first two are locked, so the marine goes to the Teleporter Access, where he meets Dr. Ian McCormick. He tells the marine that he's one of those who are responsible for teleport accident that caused Hell's invasion to the base, and that it happened right after Betruger took the Soul Cube with him to the portal. He also tells that he can activate the teleporter so that the marine can use it to travel further into the labs, but he needs the plasma inducer and asks the marine to retrieve it in Operations, and unlocks the two other doors for the marine.

If the marine goes to Operations first, he encounters a locked door and has to go to Security & Bio Labs to unlock the door, or he can go there straight away. Upon arriving at the Security & Bio Labs, the marine finds out that Security is in lockout due to Halon system being active, so the marine has to go through Bio Labs to turn it off. At some point in Bio Labs the marine enters a large room with hazardous materials stored in boxes on the wall, with an automatic manipulator used to access them. In the same room the marine should notice a vent shaft on the right wall, connected to a ledge. This is where the marine has to get to proceed further. To do this the marine needs to use the manipulator to extract one of the crates that is closer to the ledge and, after the manipulator placed the crate near the control panel, press the button to load it back and then jump on the crate. During the time when the manipulator is moving to load the crate back, the marine has to use the opportunity to jump from the crate to the ledge (when the crate is closer to it).

Going several rooms further, the marine manages to find the room where the Halon system can be turned off, and then accesses Security, where he's able to unlock the door in Operations. The plasma inducer is found in one of the rooms behind that previously locked door. Upon returning and bringing the plasma inducer to McCormick, he activates the teleporter in the next room (and also gives the marine valuable information about the teleporting experiments), and the marine uses it to get the northern part of the sector 2.

Locker/door codes[edit]

For the sources of the codes, see Doom 3 locker codes.
  • Storage locker #112 - Storage: 538. Contains: shotgun, cells x4 (x2 on Veteran/Nightmare), armor shards x5.
  • Chief M.Abrams' office: 931. Contains: BFG 9000, med kit (large).
  • Storage locker #116 - Storage: 972. Contains: plasma gun, BFG cell, med kit (large), security armor.
  • Storage locker #114 - Storage: 715. Contains: backpack, clip (large), security armor.


  • In Main Lobby, there's a small button hidden in the side of the reception desk, which open a weapon compartment in the same room.
  • There's a weapon cache in glass compartment in Records Office. To access it, move a crate near where a glass panel is missing and try to crouch jump through the window.
  • In Teleporter Control Lab corridor there's a spot with blown up wall with cable coming down from the ceiling, and a small and a large crate. Climb those crates and a small compartment can be seen in the wall with a security armor in it.
  • In Delta Operations hallway with offices (patient cells) there's a spot with two small staircases. There are gaps between each of them and the floor, which one can crouch into and find some items there.
  • In Delta Bio Labs lobby, there are items hidden behind several machine blocks. In the same room there's also a security armor hidden under the staicase.
  • In Examination Room D2-1 one can find a small glowing button in the dark corner of that room, which opens a compartment with a health station and another one on the other side of the room, with ammo.
  • In Hazardous Materials room, the player is required to reach the right ledge to proceed through the vent shaft connected to it. The player can also notices another shaft on the left ledge, but it's closed. However, if the player reaches it by extracting, and then riding on crate #4, the shaft will actually open upon getting close to it, and will contain several armor shards, a large cell pack and two large med kits.


  • On the original Xbox version of the game this level is substantially shorter and is called Delta Labs - Level 2 North.
  • In the very beginning of this level, there's a closed elevator to the left from where the player starts. If the player comes close to its doors, it will open and an imp will spawn if the player gets very close to the edge of the elevator shaft. If the player jumps into the elevator shaft (or is pushed there by imp's teleportation) and dies, Betruger can be heard laughing at the player.
  • In the teleporter room, the marine can see the room where he will have to go to get the BRD access card in the next map. If the player accesses that room via noclip, they will discover that, in fact, said keycard is actually there in this map as well and can be picked up, and even includes the zombie that is guarding it (the one that pretends to be a corpse).
  • An imp will spawn in Delta Operations Administration if you destroy three lights.
  • There are multiple Easter eggs in the zombie detention area. The offices and cells are named, presumably indicating the names of some of the zombies being detained therein - Steve Rescoe, Matt Hooper, Mal Blackwell, Christian Antkow and Jerry Keehan. These names are of id Software staff members. One of the detained zombies in particular will repeatedly bang his head on the window and occasionally make a farting sound while saying "Mmmm boy!" (a phrase also referenced in the PDA found in this same area). This is an inside joke regarding level designer Jerry Keehan.
