There's not one but two big sales going on through Steam this weekend. Until Monday, you can pick up the Overlord and Crysis series for cheap through digital game store Steam.

Overlord, Overlord: Raising Hell, and Overlord 2 are 75% off for the weekend. Crysis and Crysis Warhead meanwhile, are 50% off. The deal applies to both the individual games as well as Overlord Compete Pack and Crysis Maximum Edition, the discount bundles containing all of them.

The Crysis price reduction seems to be for yuks. The Overlord sale, though, coincides with the Steam release of Overlord: Raising Hell, Overlord's official expansion.
