IGN's Direct2Drive game download site is going nuts (nuts, we say) with their newest sales deal. From now until May 31 a large number of their tiles from the 2K Games library have had their prices cut 50 percent off their normal amounts. There's quite a few cool deals here if you have a few extra dollars.

There's quite a few titles on sale for just $9.95 including BioShock, Civilization IV, Prey, Serious Sam Gold and more. And if you have always wanted to try out the classic X-Com game series, this sale has a bundle of all five X-Com game titles for just $7.50. That's a steal in of itself.
