An ominous title portends a dark, twisted adventure. Prey begins as a sane existence on Earth. As you'll soon find out, the game doesn't stay so sane.

Twisting halls, spinning gravity and vertigo-inducing portals make up the bulk of Prey's complicated environments. Throughout these twisted worlds you'll find challenging puzzles around almost every turn. And then you've got alien baddies to worry about, including a host of gruesome bosses.

• Basics: Basic tips and strategies to help you throughout the game, plus developer tips and pointers straight from the makers of the game.
• Walkthrough: Complete Prey walkthrough with strategy for conquering all 22 levels and tips for defeating all bosses.
