Shack PC PSA: Half-Off DiRT 2 and Dawn of War 2, Aliens vs. Predator Classic at $5 and Other Deals

Once again, PC digital distribution outlets are celebrating the impending weekend with a rash of deals and discounts, including the option to play Zero Gear for free.

Aliens vs. Predator Classic and Dawn of War II

Alongside a half-off deal on DiRT 2 ($19.99), Steam is now selling Rebellion's original Aliens vs. Predator at $4.99. It's not technically a discount, mind you, but with all those fond memories and Rebellion's new AvP due next month, it's worth noting.

These are joined by several others offers, including half-off Warhammer 40,000: Dawn of War II ($19.95 via D2D) and AI War: Fleet Command ($9.95), as listed below:
