If you have an Xbox One and an Xbox Live Gold subscription, you can try out one of the best strategy games in recent years for free this weekend. That's because the Xbox One version of XCOM 2 is free to play between today and Sunday, May 6.

All you have to do is download the free trial from the Xbox Store. If you enjoy it and decide to purchase the full game, you can get XCOM 2 or XCOM 2 Digital Deluxe from the Microsoft Store for 67% off. The War of the Chosen expansion is also available for 25% off. If you do make the purchase, any progress you make during the free play weekend will carry over into the full game.
