Gray Matter Interactive Studios, Inc. was a computer game developer, which was acquired by Activision in January 2002. Gray Matter was previously known as Xatrix Entertainment, Inc. Towards the end of development for Call of Duty 2: Big Red One in 2005, Gray Matter was merged into Treyarch, and the team responsible for titles like Return to Castle Wolfenstein is no longer recognized by that name. Some of the Gray Matter team still resides at Treyarch, although its founder and several executives from the former studio have found employment elsewhere.
