Killzone: Liberation is a third person shooter developed by Guerrilla Games, released for the PSP in 2006. Unclejun was able to find a pre-production build of the game (dated august 2006, about 2/3 months before the official release) that contains some nice debug rooms and options!
Thanks to Unclejun for the contribution!
