Watch the mysterious and powerful Songbird pursue Booker DeWitt and Elizabeth, who are trying to make a desperate escape from the sky-city of Columbia, in the launch trailer for BioShock Infinite!

BioShock Infinite puts players in the shoes of U.S. Cavalry veteran turned hired gun, Booker DeWitt. Indebted to the wrong people and with his life on the line, DeWitt has only one opportunity to wipe his slate clean. He’s one man, alone. And the followers of the Prophet Father Comstock will stop at nothing to keep Booker from his Quarry.

But with an arsenal of weapons and the incredible powers granted by Vigors, Booker deals death from above on the Sky-Lines of Columbia. And the girl he’s there to rescue might turn out to be the partner he needs to survive.

Developed by Irrational Games, 2K Games will release BioShock Infinite for the Xbox 360, PlayStation 3 and PC tomorrow.
