Delta Complex: Union Aerospace Research Division

Delta Complex: Union Aerospace Research Division is the twenty-first level of Doom 3. From hereon, there will be no more zombies other than commandos. The ticks make their first and only appearance. Once more the player loses their weapons on the journey back from Hell (with the exception of the Soul Cube) and must collect them all again. The player comes across a wounded Swann, who tells him to take his PDA and that Sergeant Kelly is working with the demons.
