Delta Labs - Level 4: Union Aerospace Research Division

DELTA LABS - SECTOR 4 - "Delta Labs - Sector 4 houses the third generation transfer portal. All teleporter destination research is classified. Only top level personnel have access to the central control and activation grid for the primary test chamber."

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 a cutscene. Betruger sends the player to Hell via the main teleporter after the battle.

AREAS IN DELTA LABS LEVEL 4:
 * Air Lock
 * Delta 4 Junction 1
 * Delta 4 Junction 2
 * Delta 4 Security Check-In
 * Delta 4 Main Ready Room
 * Delta 4 Security
 * Delta 4 Transference Lab 001

Walkthrough
This level is very short, all the player needs to do is go through the few halls, collect the supplies from a 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, also 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.
