Oh, brains. You are as delicious (to zombies) as you are useful (to anyone running from zombies). You're also apparently quite explodable, as evidenced in this colorful cartoon-like physics game BrainSplode!. Created by Rust Red Games, all you've got is a cannon, some highly-useful missiles, and a few mid-air power-ups that help you control things. Oh, and an inexplicable hatred of squishy pink brains.
