XCOM: Enemy Unknown is one of the best games of the last few years, a razor-sharp update of a classic series, packed full of engaging, tense strategic combat and full of opportunities to make really bad decisions that will get all your soldiers killed.
If you’ve yet to try it out for some mad reason, you can do so over the next few days - developer Firaxis is holding a free Steam weekend for the game, from now until September 13.
During that time the game will be available for 75% off. Also available is upcoming sequel XCOM 2. There’s no pre-order discount, but putting down your money early will earn you the Resistance Warrior Pack, which includes various cosmetic items for your troopers, as well as an experienced veteran to add to your barracks form the start of the game.
XCOM 2 is out on February 5, 2016.
