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.
