Tyler Bates, the man behind the music for 300 and Watchmen is also the man behind the music for Army of Two: The 40th Day. See him talk about what he's done.
Perhaps it isn't all that interesting to some, but I'm always fascinated by the approach Hollywood and television composers take when developing music for video games. Tyler here packed the tracks he created full of sounds in order to make sure that every gameplay decision would be covered. It must have been a real challenge, but the man who scored The Day the Earth Stood Still and Rob Zombie's Halloween movies was more than up to the task.
