Teenage Zombies: Invasion of the Alien Brain Thingys (Nintendo DS)

Parents need to know that this game stars a trio of high school-aged reanimated corpses engaged in a fight against an invading army of floating brains. The undead kids wage war using their hands, tentacles, intestines, and a small arsenal of imaginative power-ups, including soapy vomit, a vacuum arm, and a skateboard with monster-sized wheels. It's not as graphic as you might think. There's no real gore (the intestine attack is simply a black and white line that zips out from a zombie's midsection to smack enemies), and the little amount of blood that is shown is cartoon in nature. The most disturbing part of the game is simply that the protagonists are dead teens who eat "brain meats" to replenish their health, though it's worth mentioning that they only munch on the cerebrums of evil aliens intent on destroying the world. The game's suitable for mature tweens.
