expired Max Payne 3 - 66% off on Steam; $16.99 USD
A weekend sale on Dampf. Max Payne DLCs, Arma 2 & addons, and Braid are also heavily discounted on Vapeur. If your brain is unable to handle games with more than 6 keys, pass on Arma and get a Call of Duty game instead, or Serious Sam. Operation Flashpoint and the Arma series are very rewarding though to grognards who take the time to learn the UI and mechanics.
