Enemies: 16x Imp, 20x Trite, 19x Zombies, 10 Marine-Zombies

A guide to the enemies in Doom 3, including Imps, Trites, Zombies, and Marine-Zombies, with details on their numbers and locations within the game.

This section details the enemies encountered in a specific area of Doom 3, including 16 Imps, 20 Trites, 19 Zombies, and 10 Marine-Zombies. The walkthrough also includes information from PDAs found in the environment, providing lore and context.

Upon leaving the bay door, players will find an open cabinet and a PDA. The PDA contains user data for Samuel J. Harding, an Engineer, and audio logs and emails. One email from James Torbin mentions repairs on door A32 and expresses unease about artifacts shipped into the Delta Complex. Another from Karl Cullen requests check on turret gun mounting brackets, with a reply from Sam confirming the repair of rattling brackets caused by 'Mixom bolts'.

Players then enter a train and activate a panel to start the monorail. A man inside warns of the danger and mentions his partner who never returned. After the ride, the objective is to manually override the monorail airlock systems.

Leaving the train, players will encounter a large door. Upon opening it, a Commando-Zombie attacks. The subsequent room is filled with enemies: approximately 2 Commando-Zombies, numerous Imps, and Marine-Zombies. The recommended tactic is to clear all enemies first, then search for items. Loot can be found near the far door, under the stairs, and a PDA is located near the room's entrance.

This second PDA belongs to Gary Ross, Lead Engineer at Site 2. It contains user data and emails. One email from Delta Security confirms the Automated Defense System at the Delta Labs entrance is operational. Another from Central Security confirms the Junction 5, Site 2 Airlock code has been updated to 826, allowing manual override of automated rail sensor systems for tests requested by Gary Ross.

A door on the upper floor leads to a small room where players must watch out for a Commando-Zombie. Upon entering this room, 4 Trites will enter the larger room, requiring players to be vigilant. Another PDA is located in this area.
