The official THQ online store (which has the new logo that's look like it's asking, "THQ?") is sporting some spiffy sales this weekend, offering some pretty great games for just a few bucks. The highlight of the sale is probably Metro 2033, which for the PC is only $10. But you can also find Company of Heroes: Gold Edition for only $7.50, the underrated (I said it) Darksiders for $10, and Red Faction: Guerilla and Titan Quest: Gold Edition for only $5 a piece.
They're not all winners (hey there, World of Zoo), but if you need to catch up on some PC titles, THQ (?) has you covered.
