Quick review for a quick game.
This game is a departure from the typical "demo" format of game marketing. Rather than letting you see a small, usually tutorial-laden snippet of the full game, Case Zero entices you with a unique location and story, progress that carries over into the full game, and achievements. Well, it worked. I never played the first game, and wasn't particularly excited for the second, but now I'm looking forward to the release of Dead Rising 2. It's just fun to carve through wave after wave of zombies with a weapon made from random junk. It's not perfect - clunky conversations, minor control oddities, and long loading times are present - but it's worthy of the purchase price.
