"Your Hell awaits!"

Delta Labs - Level 4: Union Aerospace Research Division is the nineteenth level of Doom 3. Hell knights are introduced in the cutscene.

Summary[edit]

Spoiler Warning: Plot details follow.

The level begins with Betruger taunting the marine, gloating that the Soul Cube is in Hell and will never be found. The marine enters Delta Level 4, and finds bloody skeletons littering the hallways. Worse, demoralizing messages have been written on the walls in blood.

The marine finds the Main Portal in Delta, encountering only a couple of chainsaw zombies along the way. Betruger is waiting in the control room above. He activates the portal and summons a pair of Hell knights who are chasing a scientist in a biohazard suit. The Hell knights kill the scientist and then turn their attention to the marine.

The marine battles and kills both Hell knights. However, the Portal's energies expand and suck the marine into it, transporting him to Hell.

Spoilers end here.

Trivia[edit]

  • Rather infamously, one of the chainsaw zombies on the level wears a party cone.
