|Doom 3 maps|
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 corpses, 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.
