According to EB Games, the Xbox version of DOOM 3 will feature some special content in the form of a collectors edition release. Similar to what Microsoft did with Halo 2, the Collector’s Edition will feature behind the scenes videos, Doom 2 and Ultimate Doom (both will feature split screen multiplayer action).
Expect an official word from Activision shortly. The rumored release date for the title is March 15. More on the story as it develops.
