Delta Labs - Level 4: Union Aerospace Research Division

Delta Labs - Level 4: Union Aerospace Research Division is the nineteenth level of Doom 3. This is a very small level, consisting of a few corridors and the main battle. All the halls, and corridors here are completely littered with skeletons, blood, body parts, and messages such as "SUCCUMB", "DIE", "SUFFER", "FEAR" written in blood on the walls. Hell Knights are introduced in the cutscene and the player encounters the party hat Chainsaw Zombie here. Betruger sends the player to Hell through the main teleporter after the battle.

Walkthrough
This level is very short, all the player needs to do is go through the few halls, collect the supplies from the one locker, kill a couple of chainsaw zombies, and go into the teleporter room to confront two Hell Knights. Space for fighting the beasts is limited, and having to fight two adds an extra challenge. The BFG comes in handy here, but if the player never managed to find it earlier, the Chain Gun is by far the next best option. Compared to the rocket launcher, the Chain Gun puts out damage for much longer before needing to reload and reloads more quickly, plus there is no chance of splash damage from the confined space. The other weapons such as the Machine Gun, shotgun, and chainsaw are too weak to work very well on the duo.
