Enemies: 20x Imp, 2x Pinky, 6x Zombie, 10x Marine-Zombie

Encountering 20 Imps, 2 Pinkies, 6 Zombies, and 10 Marine-Zombies in Doom 3? This guide details their locations and strategies for overcoming these threats in Alpha Labs.

This section details the enemies encountered in a specific area of Doom 3, including 20 Imps, 2 Pinkies, 6 Zombies, and 10 Marine-Zombies. As you enter the area, a cutscene will play, revealing that the events are part of an experiment.

You will immediately face a Zombie-Marine. After defeating it, observe the screens for messages related to Alpha Labs. Continue down the hallway, eliminating an Imp and 2 Marine-Zombies. Enter a small room to find and kill a Zombie, then collect a PDA and a Video Disc. The PDA contains information about the 'Alpha Labs Introduction' video and user data for Alan E. Dorweiler, including an email from Ethan Person about ammunition and armor in a storage cabinet with code 586. Another email from Ethan discusses UAC Corporate sending Elliot Swann and his bodyguard. A third email is from martianbuddy.com regarding online pharmacy services.

Use the health machine and the cabinet code 586 to acquire armor, ammo, and grenades. Proceed through the only available door. An Imp will attack; defeat it. Continue onward, where a Zombie will throw a barrel at you. Avoid it and kill the Zombie. To the left of this room, you'll find an injured Marine. Speak with him and attempt to open the lock, which will update your objective to 'Gain entrance into the Alpha Labs'.

Return to the area where you found the previous PDA. An Imp awaits; defeat it. Go back to the main hall of the Administration section. Two Imps will open a door for you; kill them. Enter the new area, and after moving forward, the lights will go out, and two Imps will drop down, one in front and one behind you. Continue, defeating 2 Marine-Zombies. Explore for additional items, then open the only other door in the area. Enter a small office, collect items, and use the computer to open another door. A cutscene will play, introducing a Pinky that attempts to break down the door before going through the glass. Defeat the Pinky with your shotgun. An Imp will emerge from the unlocked door; kill it and then enter the door yourself.
