In what we assume is an attempt to capitalize on the recent press coverage of Borderlands 2, Steam has cut 75% off all Borderlands content, including the vanilla title, the "Game of the Year" edition and all downloadable content. If you've already explored the dilapidated planet of Pandora, Steam also offers 75% off Counter-Strike, while you'll find 50% off Homefront, Dragon Age 2 and Thief: Deadly Shadows as well as 66% off Civilization V at GamersGate.
