Doom 3 Walkthrough Screenshot 17. This zombie crawls out from the left. Grab the armor and cells.

Doom 3 Walkthrough Screenshot 18. Defeat this Imp and two Z-Sectors in the next room. Here I'm using a shotgun, but I found it best to toss a grenade in as soon as the door opens, then back out. Shells and a medkit and a clip are straight ahead.

Doom 3 Walkthrough Screenshot 19. A fat zombie is behind those crates below, and an Imp is lurking as well. Toss some grenades to take them out before calling the lift.

Doom 3 Walkthrough Screenshot 24. Backtrack a bit to the terminal on the left, which opens the crawlspace on the right. Armor and a medkit are inside. Continue up the stairs where you tossed the grenade a moment ago.

Doom 3 Walkthrough Screenshot 25. An Imp emerges from the right. On the catwalk is a medkit. Under the catwalk are grenades and armor. Ignore the middle catwalk on the right. Instead, continue to the door dead ahead.

Doom 3 Walkthrough Screenshot 29. Proceed to the middle catwalk you ignored earlier. Defeat this Imp that spawns behind you. Pass through the door at the end of the catwalk. Update: Dave Matos writes, " There's plasma and other ammo on the catwalk above you, behind the imp that just spawned in the screenshot. You can access the catwalk by hopping onto the machinery in the room. By jumping onto the catwalk, you can also access the 2nd floor of the adjoining room, where you can find some armor, etc. "

Doom 3 Walkthrough Screenshot 30. Defeat another Imp then grab the medkit and armor beneath these stairs. Be ready for a Z-Sector to attack from the stairs. Continue up the stairs and pass by the mechanism while it is retracted.

Doom 3 Walkthrough Screenshot 38. Use the console to activate a sentry bot.

Doom 3 Walkthrough Screenshot 39. Follow the bot as he battles Z-Sectors, Cacodemons and Imps. Again, don't be in such a rush to keep up that you miss the medkits, ammo belt, and clips along the way.

Doom 3 Walkthrough Screenshot 40. The bot comes to rest at this lift. Ride it up to Satellite Control.

Doom 3 Walkthrough Screenshot 41. Grab Rob Finch's PDA for some background.

Doom 3 Walkthrough Screenshot 42. Follow the corridor to Satellite Control. Grab the armor vest on the counter.

Doom 3 Walkthrough Screenshot 43. Use the console on the left to receive a warning from Swann. He doesn't want you to send the transmission.

Doom 3 Walkthrough Screenshot 44. The console's options are updated. If you choose transmit, Swann berates you and threatens to be waiting for you in Delta. Cancel the transmission and he congratulates you but Sarge orders you to get back to the console and send the message -- impossible because the console won't let you. Either way it doesn't really matter because Betruger sends the message if you don't -- hey, this isn't an RPG.
