Casual Gameplay: How the zombies have fallen. Once they were a terrifying, cannibalistic reflection of our basest impulses, but decades of B-movie hackery have reduced them to an iconic geek totem, like ninjas or pirates or nuns. The Return of the Living Dead plastered them with a goofy catch-phrase, and now, except for a couple of attempts to resurrect them as drooling sprinters, they're pretty much a joke. Just look at them here. They've literally been turned into plant food, getting pelted to bits by peas and cabbage.
