I finally own this game. I had been wondering about it as it seemed like a more tongue in cheek Gears of War.
I still haven't gotten the chance to really sit down and play it... but if I ever do I will give away a CD key for a copy somewhere in the middle of the run as I have a spare too!
The Main theme (and in fact, the rest of the soundtrack) is composed by Krzysztof Wierzynkiewicz and Michael Cieleck. A very powerful theme, very suited for an epic but over the top action game.
Bulletstorm is a 2011 first-person shooter video game made by Polish developer People Can Fly and the American company Epic Games, and is published by Electronic Arts for the PlayStation 3, Xbox 360 and Microsoft Windows. The game was released on February 22, 2011 in North America and on February 25, 2011 in Europe.
The game is distinguished by its sense of style and crass humor, rewarding players with points for performing increasingly ludicrous and creative kills. Bulletstorm does not have any competitive multiplayer modes, preferring instead to include cooperative online play as well as score attack modes.
