The Humble 2K Bundle is now live, allowing you to pay what you want for BioShock, The Bureau: XCOM Declassified and The Darkness II. Those that choose to pay more than the average (currently $5.30) will unlock BioShock 2, Mafia II and Spec Ops: The Line with more games coming soon. If you opt to pay $20 or more, you’ll also get all the previously mentioned games along with XCOM: Enemy Unknown and BioShock Infinite.
There is a minimum of $1.00 in order to receive Steam keys from the Humble 2K Bundle, but other than that you can pay what you want to support two charities: Action Against Hunger and American Red Cross. The Humble 2K Bundle will end two weeks from today (July 22, 2014 11:00 AM PT / 2:00 PM ET) so act fast.
