Up until January 20, you can try Metro: Last Light Redux, Metro 2033 Redux, and Override: Mech City Brawl for free on Xbox One if you have an Xbox Live Gold Subscription.
This is part of Microsoft’s Free Play Days promotion, which devotes a couple days towards offering free trials for games. You have full access to the games until tomorrow.
Both Metro games in this promotion are the definitive Redux versions, which have upgraded graphics and all DLC. As for Override: Mech City Brawl, it’s also free to try on Steam this weekend. The Steam promotion ends tomorrow as well.
