The Humble Bundle has launched a new tiered bundle from publisher 2K, offering up to $209 worth of PC games.

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.
