Dead Rising, a game of blood, gore, dismemberment and black humour is, it has to be said, an office favourite. We embrace it with huge arms of love. Why? Well a) because, well, zombies rock. But b) they rock with bells and grating power chords on when you blow their stupid rotting heads to bloody smithereens with a mighty shotgun blast and slice them in half with a well-aimed axe blow to the torso.
