A playable demo for Bulletstorm is now available, offering the expected sample of the first-person shooter from Epic Games and their People Can Fly studio. The demo is available through Games For Windows and Steam. We don't have details on the demo, but the announcement does have this blurb on the game:

Since the arrival of Grayson Hunt and his band of space pirates, Bulletstorm has received worldwide acclaim, with Yahoo! Games calling it, “the most original shooter in years,” and MSN declaring Bulletstorm “a fantastic game.” Bulletstorm tells the story of Grayson Hunt and Ishi Sato, ex-members of an elite military force called Dead Echo, now mercenaries on the run across the galaxy. Stranded on Stygia, a paradise lost that has been overrun by rampaging freaks, flesh-eating plants and creatures the size of skyscrapers, their main objective is to survive long enough in order to exact revenge on the one person responsible for their plight.
