Pay $1 or more and you'll receive BioShock, The Darkness 2 and The Bureau: XCOM Declassified. Pay more than the average - currently $7.41 - and you can throw in BioShock 2, Mafia 2 and Spec Ops: The Line.
Pay more than $20 and you also get BioShock Infinite and XCOM: Enemy Unknown.
There's also the promise of more games to be added to the bundle.
Anyone paying over $1 also receives Steam codes for the games they are eligible for.
