Just Cause 2, pretty badass trailer

What's cool is actually the way the video plays out. You play as Nico, the super-secret ace in the Agency's sleeve, who tackles the military regime in Panau in pursuit of his former boss and mentor Tom Sheldon. It seems going rogue with military intel and cash is not something the Agency takes too lightly.

So you can actually branch out and "play" through different scenarios by clicking on different prompts when you reach a certain part of the video. Kinda like a "choose your own story" book. Neat.
