Released today on the iPhone, and the iPod touch, Trapped: Undead Infection is a nice and cheap ($1.99) game you can get for your Apple devices.
Trapped: Undead Infection has tense, thrilling game play that features cool effects using darkness and light, claustrophobically narrow rooms, and nefarious brain-eating zombies. You play a scientist in the near future trapped in a large bio-research facility swarming with the undead. As you wander the shadowy corridors and rooms, defend yourself from the zombies with pipes, stun guns, handguns, and machine guns. Use intelligence and strategy to solve puzzles as you move through the large, open-ended levels. A detailed map helps you escape, and spooky sound effects add to the intense atmosphere.
