Jack Campbell

Jack Campbell is a character from Doom 3 who wields the most powerful weapon in the game, the BFG 9000.

Jack is seen with Councilor Swann in some of the cutscenes, although during gameplay the player gets a chance to watch him blast a group of Trites through a window using the BFG 9000 at very end of Alpha Labs Sector 4, just before first contact of Vagary.

Jack considers himself to be the "damage" part of "damage control" (Swann being the "control"). Wielding his BFG 9000, Jack Campbell is the bodyguard of Councilor Swann and protects him while they attempt to escape the demon invasion. Jack does not have a high opinion of Doctor Malcolm Betruger, who he considers to be stubborn and does not think that he will bend in to any of UAC's demands and that Swann's mission has no point. While seen mostly just in cutscenes, he is seen ingame three times: In the pre-invasion Mars City after the cutscene involving Swann and Betruger he can be seen walking out of a door after Swann, again when he kills some Trites, and for the third time when he encounters the Marine. He is badly wounded, and advises the Marine to watch out for Sergeant Kelly (Now Sabaoth), who took his BFG 9000. He dies shortly afterwards muttering the words: "Sarge... find him... you gotta find him... my gun... he's got my gun...".

Trivia
If you kill Campbell when he is holding his BFG suitcase, or when he is holding the BFG, his body cannot be gibbed up, and you can obtain his BFG 9000. However, you can gib him in the CPU complex.
