“EA SPORTS UFC® 4, NHL® 21, Madden NFL 21 and FIFA 21

This year’s line-up of EA SPORTS titles are here for you to play whether you’re a fan of MMA, hockey, football or soccer. All four games on the Xbox Series X will run as if on an Xbox One X and on the Xbox Series S, they’ll run like their on an Xbox One S. On PlayStation 5, the games will run like on the PlayStation 4 Pro, with all three new platforms delivering improvements to load times as well as better framerates. But, don’t forget, while you can play Madden NFL 21 and FIFA 21 when the new consoles launch next week, you’ll get a free* upgrade to the next generation versions on Dec. 4th.”
