New details of Killzone's PSP debut have been revealed in this month's Official PlayStation 2 magazine.

The game is called Killzone Liberation and is scheduled for release at some point this year, although at this point there is no solid date. Guerrilla Games has abandoned the FPS gameplay of Killzone on the PlayStation 2 and instead opted for a Metal Gear Solid like fixed camera approach.

Once again you must fight off the evil Helghast, who now come in a variety of different guises, on a mission to rescue hostages from within the Helghast camp. More news as we get it.
