One of the eight games coming to Xbox Game Pass in April was announced during the premiere episode of Inside Xbox. Cities: Skylines will be coming to Game Pass for subscribers to jump into. As of right, now we only know about this one game but the other eight games will be announced at some point over the next three weeks

We still have one more game that will be added to Game Pass in March once Sea of Thieves is released on the 20th. It feels like a long ten days for players who are excited about playing the new pirate adventure from Rare. If you’re looking to get into the beta then you may have some issues. Right now Rare is not allowing any more players until some issues have been fixed. We will keep you covered on when you can join the fun.
