PlayerUnknown's Battlegrounds and Pro Evolution Soccer 2019 are free for a limited time on the Microsoft Store according to each games listing. This is believed to be part of Microsoft's upcoming X018 event, which has gone live a bit earlier than intended.
At this moment in time its not clear whether this is a full-on giveaway or if each game is just free to play for a limited time. Either way if you have any interest in either game it might be worth claiming them sooner rather than later.
