I was a fan of DoubleSix's Burn Zombie Burn, an arcade-style shooter with some very well-implemented scoring and a whole mess of zombies to set ablaze. As such, I'm quite excited for the follow-up, All Zombies Must Die, which is more of a story-driven game with RPG elements and still more zombies.
Truth be told, it reminds me a lot of Zombies Ate My Neighbors, one of my all-time favorite games from the fourth console generation. If that doesn't perk up your ears, maybe watching this video introducing the game's characters will. You should also read our preview of the game from back in August.
