Humble 2K Bundle: Pay what you want for BioShock, The Darkness and XCOM

Humble Bundle and 2K are teaming up for the second time this year, offering gamers the chance to pay what you want for a number of 2K-published games, including BioShock and XCOM.

Available now, the Humble 2K Bundle lets you pay any price you want to buy BioShock, The Bureau: XCOM Declassified and The Darkness II. However, if you pay more than the average price, currently $5.28, you can also get BioShock 2, Mafia 2, and Spec Ops: The Line. It gets better though. By paying $20 or more you can also unlock XCOM: Enemy Unknown and BioShock Infinite.

So basically, you can get the entire BioShock trilogy plus a ton of other award-winning 2K games for just $20. And you're also supporting charity. The Humble 2K Bundle will be available for two weeks and ends on Tuesday, July 22.
