Fallout Extreme

Fallout Extreme is a canceled, squad-based, first- and third-person tactical game for the Xbox and PlayStation 2, using the Unreal Engine and developed by Interplay's 14 Degrees East division. It was in development for several months in 2000, but never had a concrete development team and had not been developed past conception.

The game was never officially announced, and its existence was virtually unknown until detailed information about it was released in January 2010.
