Here's a deal you can sink your teeth into: this weekend only, pick up the acclaimed first person shooter Prey for just $US 4.95.
In Prey, players enter a living spaceship which enslaves alien races and devours humans for lunch. Prey turns the first person shooter genre upside down with awesome new gameplay features like wall-walking and gravity flipping, making for intense single-player and multi-player experiences.
Prey is built on a heavily modded version of the Doom 3 engine and is developed by critically acclaimed developer Human Head Studios under the direction of 3D Realms.
