Enemies: 8x Imp, 15x Zombie, 8x Marine-Zombie

A Doom 3 walkthrough guide detailing enemy encounters, including 8 Imps, 15 Zombies, and 8 Marine-Zombies, along with item locations and PDA information.

This section details enemy encounters and item locations within Doom 3. You will face 8 Imps, 15 Zombies, and 8 Marine-Zombies.

Upon entering the initial room, you will acquire a pistol, ammunition, and armor. Proceed through the next door to search for a missing scientist.

Objective: Reach Old Com Building.

In the room containing a crane, shoot the operator in the head to obtain his PDA. This PDA belongs to Daniel M. Young, the Crane Operator.

After exiting the room where you obtained your pistol and flashlight, you will find a room with a large chasm, a crane, and a locked room on the opposite side. Operating the crane allows for a 90-degree rotation. Before exiting this room, look left for a small ledge with a medpack. By jumping over the railing and looking left, you can spot a rope spanning the chasm. Walking across this rope leads to the other side.

Continue following the path. In a room with a broken panel and a scared individual, note the panel he is operating. The next room will experience a power outage, requiring the use of your flashlight. Follow the path, collect bullets from a box, and shoot the Marine to obtain his PDA. Open the airlock.

The PDA of Grant F. Baston, Services Supervisor, can be found two rooms later, in the area where a character states, "Why don't you get your fat ass down here and do it yourself?". This PDA contains an audio log about unexplainable events and mail regarding security cabinet codes. The mail from UAC Security provides the code 531 for the Energy Stabilization Unit's security cabinet.

Using the code 531 on the cabinet will yield additional armor and shells. Continue onward through the only available path. You will encounter a broken panel and a frightened individual. In the subsequent room, the lights will fail, necessitating the use of your flashlight. Follow the path and collect ammunition from a box. Shoot the Marine to acquire his PDA, belonging to Mark B. Ryan, a Security Officer. Finally, open the airlock.

According to Synnystr, you can walk along the walkway and jump over the left railing before turning to proceed through the next door. This will lead you to a cache of armor and bullets located beneath the walkway.
