Last week we reported on the Humble 2k Bundle which offers up many titles from 2K for dirt cheap prices. At the time we reported it, there was a section which would be unlocked at a later date. That day has come and now we know what that game is: X-Com: Complete Pack.

This collection of games includes X-Com: Apocalypse, X-Com: Enforcer, X-Com: Interceptor, X-Com: Terror from the Deep and X-Com: UFO Defense. The collection unlocks if you pay more than $8.05.

As for the rest of the games on sale: for any price you will get BioShock, The Darkness II and The Bureau: XCOM Declassified. For more than $6.49 and you’ll unlock BioShock 2, Spec Ops: The Line and Mafia II. Paying more than $20 will get you BioShock Infinite and XCOM: Enemy Unknown.

This sale will continue until July 22. To take advantage of it while it lasts, make sure to follow this link.
