The appearance of Kratos, the star of the God of War series, on the PSP isn't at all surprising. In fact, he's just the latest in a long line of staunch Sony loving characters that have made the jump to the handheld world to try and help the PSP catch up with the DS in the sales stakes.
The God of War games have constantly been all about masses of huge battles against a plethora of beasties, including hulking great multi-storey examples to be taken down via some handy quick time events. There are no subtle plot points, or stealth sections to break up the brutal nature of the combat. Nope, it's just solely about lopping off limbs, and causing as much bloody death as your button mashing fingers can manage.
