A slew of notable games can be picked up for under 20 bucks. At the time of this writing, The Darkness 2, Max Payne 3, Mortal Kombat: Komplete Edition, Ninja Gaiden 3, Quake 4, Street Fighter x Tekken, Silent Hill: Downpour, Soul Calibur 5, SSX and Syndicate are all available for $10. Dead or Alive 5 and the action-crazed Asura's Wrath are $11 each. Assassin's Creed: Revelations is stabbin necks on its own for $13. The Devil May Cry HD Collection is $15 and, if it offends you, a great way to pretend the reboot never happened.
The remaining offers are a bit pricier, but they're still decent deals. XCOM, Tekken Tag Tournament 2, Darksiders 2 and Borderlands 2 are $20 apiece. Dishonored is creeping in the shadows on its own for $22. Starcraft 2: Heart of the Swarm, Far Cry 3 and Metal Gear Rising: Revengeance are $28 each. Dead Space 3: Limited Edition is slicing limbs and price tags at $33. Tomb Raider's origin story is $37, leaving Call of Duty: Black Ops 2 as king of the hill at $40.
There were previous offers for great games that have already been sold out, so if you see something you like, rush it through the checkout. Of course, removing payment information from Microsoft-anything is an absolute chore. If you'd like to delete your card from their servers after your purchase, start here.
