People Can Fly and Epic, the companies behind Bulletstorm, is giving you guys a free PC game to try out. It's called Duty Calls and well, you can see who the game's parodying. It's a 700MB download, which I'm currently grabbing right now. Check out the trailer below and is it me or is the trailer eerily accurate on the plot of some COD games. I wonder if Activision's going to try and take the game down.
