If you want some backstory before Metro Last Light hits, you can pick up Metro 2033 for a very good price this week. As THQ Week kicks off, Steam has knocked the price down on the game to a mere $5. In addition, the THQ Hit collection( which includes Darksiders, both recent Red Faction games, Saints Row 2 and Homefront) has been reduced to $50. Plus, the whole THQ offering on Steam, excluding Saints Row 3 and Space Marine, is 33% off for the entirety of this week. Finally, even more discounts will be coming up in the coming days. If your not into THQ games, then you can also pick up Ancients of Ooga for $5 today only.
