IGN: For people who haven't been wise enough to follow your game, can you give us a summary of Psychonauts?

Tim Schafer: Psychonauts is the story of this kid named Raz, who's a psychic. He busts into this training camp for the Psychonauts, who are international secret agents who use their paranormal abilities to do spy work. This mystery starts to unfold at camp where kids start disappearing and he uncovers this plot by this crazy madman to steal all the psychic brains of all the kids at camp and turn them into these weapons of mass destruction and take over the world. Raz has to get back all the brains.

The really interesting thing about the game is the way he does that is -- his most important psychic ability is the ability to telepathically jump into someone's mind. And those are the levels for the game. He jumps into their imaginary world and runs around. The idea for the game came from, when you see some crazy person or just your friend who is a weird character, and you're like, what is it like inside their head? That crazy guy's talking to himself on the street, who's he talking to? My friend who thinks everything's about him, in his world is he like at the center of this crazy universe? You just try to visually imagine it and in Psychonauts you get to jump around in the world and explore it.
