Delta Labs
From DoomWiki.org
Delta Labs is one of the prominent locales in Doom 3. It is also one of the hardest parts of the game as the player fights more than a hundred demons, suffers from hallucinations and must unlock several lockers. The lack of cutscenes makes gameplay constant, though Dr. Betruger constantly adresses the player and the demons over the loudspeakers. In addition, the main portal is located at Delta Labs.
The player returns to Delta Labs after retrieving the Soul Cube to find the area in ruins and coated in growth.
Ticks are only encountered in Delta Labs in a large swarm.
Delta Labs also makes an appearance in Resurrection of Evil, though only barely recognisable.
