A while back we brought you the news that UFC welterweight champion Georges St.Pierre had been helping video game developers UFG make the fight scenes in their latest title ‘Sleeping Dogs’ more realistic, and now they’ve released a new video giving more insight into the process.

The programmers talk excitedly about getting the chance to work with the MMA superstar, and we get to see the man himself suggesting techniques for them to incorporate into the game and getting a chance to playtest it.

At one point he admits, “In life I’m a good person, but when I play I’m like the most evil person I can be!”

Later on in the video we see him mowing down a bunch of innocent bystanders in a car, so he wasn’t joking!

Check out the full behind-the-scenes look at the game, which comes out on Xbox 360, PS3 and PC in August, below.
