Something was witnessed on Amazon as well as GameStop just the other day, and that thing was Call of Duty: The War Collection. It’s a pack which includes most of the WW II themed Call of Duty titles that have been released over the years. It has Call of Duty 2, Call of Duty 3, and Call of Duty: World at War. It’s lacking the first Call of Duty though.
Call of Duty 2 was developed by Infinity Ward and released in 2005, but the other two were developed by Treyarch, while IW moved on to develop the Modern Warfare series of games. Treyarch is now working on Call of Duty: Black Ops.
This bundles seems to be for the Xbox 360 only at the moment, with a PS3 and PC version speculated to arrive later on, but it might just be an exclusive. The release date is scheduled to be somewhere in June 2010, and should sell for $59.99.
