2K Games (360, PC)
In this first-person shooter from Madison's Human Head Studios, a Native American named Tommy tries to save Earth after being abducted by aliens. Prey doesn't offer much that other first-person shooters haven't already provided, but it has an entertaining storyline and is fun to play.
The game's gravity tricks make exploring the enemy vessel a bit more than your typical hallway crawl. Charged walkways that allow you to walk straight up walls and even along the ceiling are located throughout the ship. Strange energy pads are embedded in the walls, ceilings and floors of some rooms and hallways, causing gravity to switch around when activated. As a result, you can avoid obstacles by rotating or flipping a room on its head.
The most interesting feature of Prey, however, is Tommy's ability to leave his body and stalk the enemy ship in a spirit form. That way, he can slip past force fields and bridge gaps to reach control panels that will allow him to advance when his spirit has returned to his body.
