PSX Extreme - Destroying hordes of zombies over and over can be repetitive. But there are ways to bypass the monotony with creativity and inspiration; Dead Nation is a good example. The problem with All Zombies Must Die! is that both the action and the questing system is insanely repetitive. Couple this with a few extremely irritating mechanical issues, and you’ve got an underwhelming albeit mildly fun game that gets tiresome all too soon.
