Amazon includes downloads of Metro 2033, Homefront, Red Faction Armageddon, Red Faction Guerrilla, S.T.A.L.K.E.R.: Shadow of Chernobyl and Warhammer 40,000: Space Marine, all for $12. Regularly priced, this bundle comes out to $118, so that's a savings of 91 percent. Buying all six games is cheaper than getting one by itself, so if you're in the market for any of these, it's your lucky day.
Actually, it's your lucky days: The Tantalizing THQ Medley will be on sale through January 20 as Amazon's Deal of the Week.
