Jack Campbell

Jack Campbell is a character from Doom 3 who wields one of the most powerful weapons 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.

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 twice: Once, when he kills some Trites, and again when he encounters Doomguy. He is badly wounded, and advises Doomguy to watch out for Sergeant Kelly (Now Sabaoth), who took his BFG-9000. He dies shortly afterward.
