If you have a participating PSN account, then there's currently a very cool 2K Games bundle available over at the Humble Bundle site, bagging you a lot of great, classic titles, across various Sony platforms, for very little cash.
Currently, just five dollars will get you XCOM: Enemy Unknown and Civilization Revolution II for the PS Vita. Alongside these titles you also get BioShock, The Bureau, Spec Ops: The Line, Mafia II, XCOM: Enemy Within, and Borderlands 1 & 2 for the PS3. If that wasn't enough the $5 deal also includes Battleborn and Evolve for the PS4. That's eleven games in total!
Stepping up a tier to twenty dollars will also add the excellent XCOM 2 for the PS4. That's a hell of a lot of good games for a pretty slim amount of cash, the proceeds of which can be donated to the current charity, Covenant House, which helps the homeless youth.
As usual the current bundle will be available for the next two weeks. It is required that you have a PSN account registered to one of the countries listed here. Be sure to check the link before you put down your money to avoid disappointment, followed by rage, then possibly structural damage.
