As spotted by TwistedVoxel, Microsoft has closed a loophole that allowed players to redeem one year of EA Play at $30 for four months of Xbox Game Pass Ultimate – a cheaper way of getting that amount of time on Xbox’s subscription service that would usually set you back $15 per month. Xbox recently announced it would begin celebrating its 20th anniversary which is going to see a range of promotions go live to celebrate the milestone. Amongst the announcements are a lot of ways to save on Game Pass Ultimate, if your method for redeeming the cheap subscription has now been cut off. You can also purchase some 20th Anniversary Collection at Xbox Gear, if that’s more your style. If you’re looking forward to more free games to play via the service, you’ll be pleased to know that Xbox Game Pass Ultimate and EA Play subscribers will receive multiplayer brawler Knockout City when it launches May 21 – and that’s the game’s full version, too.
