ZeniMax Media, the parent company of Bethesda Softworks (Morrowind, Oblivion, Fallout 3), has completed its acquisition of id id Software (Doom, Quake, Wolfenstein).

"id Software will continue to operate as a studio under the direction of its founder, John Carmack," vowed ZeniMax. "No changes will be made in the operations of id Software in the development of its games. All the principals at id Software have signed long-term employment contracts, assuring they will continue in their roles...at the studio."

Founded as an independent game developer in 1991, id Software is currently working on the post-apocalyptic shooter RAGE (PC, PS3, 360) and the long-awaited Doom 4.
