This is how you celebrate the holidays kids! Yes, the crazy team at People Can Fly celebrate Christmas by decking the halls with boughs of bodies. Lead protagonist from Bulletstorm, Grayson Hunt, lights up a Christmas tree all the while showing off the multiple ways you can eviscerate enemies.
Speaking of People Can Fly, you should really check out their dev blog. They have a bunch of inside looks at the development of Bulletstorm along with videos of the game I’m only just now seeing.
