THQ Week, Steam has thrown a very hefty discount on one of 2010's hidden gems, Metro 2033. The post-apocalyptic Russian shooter is currently on sale for $5, as in five bucks, as in less than a greasy, unhealthy combo meal.
Steam is also offering the THQ Hit Collection for $50, half the usual price. The Hit Collection includes favorites like Darksiders, Red Faction: Guerrilla, Saints Row 2 and ... others like Homefront and Red Faction: Armageddon. Finally, the whole THQ catalog (minus Saints Row: The Third and Space Marine) is 33 percent off this week, with more discounts coming in the days ahead.
Finally, in other Steam news, Ninjabee's Ancients of Ooga is today's daily deal, available for $5.
