Doom 3 Walkthrough - Alpha Labs Sector 2

Doom 3 Walkthrough Screenshot 1. Step off the elevator and quickly head right to see this body being floated out the door. Another body is being gibbed in the ceiling above you. Armor and a medkit are to your left as you step off the elevator.

Doom 3 Walkthrough Screenshot 2. Advance up the stairs and these two Imps spawn.

Doom 3 Walkthrough Screenshot 3. Don't miss this armor and ammo around the right corner before exiting out the door.

Doom 3 Walkthrough Screenshot 4. This Imp spawns in the doorway behind you.

Doom 3 Walkthrough Screenshot 5. The door on the left opens just enough for this Z-Sector to shoot at you.

Doom 3 Walkthrough Screenshot 6. Enter the restroom to do battle with three zombies and a maggot.

Doom 3 Walkthrough Screenshot 7. You'll find grenades in the handicapped stall, plus this medkit seen here. Climb the ladder on the right.

Doom 3 Walkthrough Screenshot 8. A radio transmission is heard from someone trapped in storage room C4. Sadly, that's the last you hear from him. Ready your shotgun and stay right as you crawl through the shaft. As you approach this cache of health and armor a maggot attacks. A weapons clip is to the right. Update: Herman from the Netherlands sends note that there are more signs of the trapped man later on.

Doom 3 Walkthrough Screenshot 9. Follow the other branch of the shaft and witness this zombie feeding.

Doom 3 Walkthrough Screenshot 10. Drop below and battle two Imps and this maggot.

Doom 3 Walkthrough Screenshot 11. Enter the security checkpoint on the right to find the feeding zombie you witnessed earlier. Both zombies arise and attack. Note the health station in the back.

Doom 3 Walkthrough Screenshot 12. On the left counter is the PDA for Andrew Chin, revealing the code for storage cabinet 038 to be 409. Also here is this security scanner, where you can see that someone is in engineering coolant control. Select "security checkpoint" to view yourself.

Doom 3 Walkthrough Screenshot 13. Return to the hallway. Grab the armor seen under the floor before passing through the door on the right, then through another door.

Doom 3 Walkthrough Screenshot 14. Pop a maggot with your shotgun and an Imp spawns behind him.

Doom 3 Walkthrough Screenshot 15. The corridor depressurizes, but you still have time for a quick view of the Martian landscape.

Doom 3 Walkthrough Screenshot 16. Pass through two more doors and show your shotgun to this Z-Sector. Watch the UAC video to learn about the MFS Compressor.

Doom 3 Walkthrough Screenshot 17. Press on and spot your fellow Marines through this window.

Doom 3 Walkthrough Screenshot 18. Defeat this maggot and two Z-Sectors attack.

Doom 3 Walkthrough Screenshot 19. On this left counter is the MFS Compressor video and Walter Connors' PDA, revealing the code 102 for storage cabinet 039. Before heading through that door ahead...

Doom 3 Walkthrough Screenshot 20. ...hop across the compressor to storage cabinet 038. Unlock it with code 409 to find a clip, grenades and armor.

Doom 3 Walkthrough Screenshot 21. Press on to battle two Z-Sectors and an Imp -- they're far enough away that grenades are a safe choice. Just when you think you're done, this maggot crawls out from the left wall -- switch to the shotgun. Note the medkit on the left. In the crawlspace behind the maggot is an ammo belt and a clip.

Doom 3 Walkthrough Screenshot 22. This medkit is tucked around the right corner. A clip and another medkit are available along the left wall. Herman from the Netherlands writes that if you walk a bit left of this frame, you can find evidence of the trapped man noted earlier: "You'll find a floor panel which is damaged, it looks like someone was scratching there. If you'd shoot that panel, it will fall down and reveal a ladder to a room with an imp, 2 clips (60 bullets a piece) and some shells. After you shoot the barrels beside the ammo, you can find security armor and another clip. When entering the room you'll hear another radio transmission, too."

Doom 3 Walkthrough Screenshot 23. Ready your shotgun and ride this lift down.

Doom 3 Walkthrough Screenshot 24. Defeat this Imp/maggot tag team.

Doom 3 Walkthrough Screenshot 25. Grab a medkit and armor on the left before continuing through this door, where you'll find a clip to the right.

Doom 3 Walkthrough Screenshot 26. It's the guy you saw on the security scanner. He offers to lead you out of here if you protect him. Time for an escort mission!

Doom 3 Walkthrough Screenshot 27. You'll have a couple false starts before this first attack. The power goes out, then you hear a loud clank, and then this Imp attacks.

Doom 3 Walkthrough Screenshot 28. Don't be in a panic to keep up with Edwards. He'll wait and you'll find goodies like this clip, shells, and medkit in the left corner before he descends the stairs.

Doom 3 Walkthrough Screenshot 29. Just after the stairs, Edwards turns left here. You turn right and take out an Imp in the corner. A bag with grenades, a clip, shells and bullets is back there as well.

Doom 3 Walkthrough Screenshot 30. The power goes out again. Edwards turns left; this Imp attacks from the right.

Doom 3 Walkthrough Screenshot 31. The glowing eyes reveal your next foe to be a maggot. Note the medkit, clip and shells on the right. Edwards spots the exit. Poor Edwards.

Doom 3 Walkthrough Screenshot 32. As your near that ladder, the lights fail and this Imp leaps out of the darkness. Edwards doesn't make it.

Doom 3 Walkthrough Screenshot 33. Another Imp has spawned behind you. Defeat both Imps then climb the ladder.

Doom 3 Walkthrough Screenshot 34. Before charging through the door at the top of the ladder, look back to find locker 039. Open it with code 102 to find armor and ammo.

Doom 3 Walkthrough Screenshot 35. Hop across these pipes to the walkway on the other side.

Doom 3 Walkthrough Screenshot 36. Crouch through this crawlspace. Crawl through spider webs, see spidery shadows and hear a strange clicking sound.

Doom 3 Walkthrough Screenshot 37. Meet your next new foe - the Trite. Pop his juices with a few rounds from your machine gun.

Doom 3 Walkthrough Screenshot 38. You're safe for the moment. Heal at this health station and grab armor and ammo here.

Doom 3 Walkthrough Screenshot 39. Ready your machine gun and activate this panel.

Doom 3 Walkthrough Screenshot 40. The service ladder doesn't extend right away, and a swarm of Trites attacks. Use short bursts on your machine gun. It only takes a few bullets to pop a Trite.

Doom 3 Walkthrough Screenshot 41. Climb the ladder once it finally extends. Another wave of Trites attacks, but you don't have to battle them. Head into the elevator on the left and the Trites won't follow. Activate the panel on the left to end the level and proceed to Alpha Labs Sector 3.
