Calling all gamers! This deal is for you.

If you regularly play Xbox or Windows PC games and want to expand your experience, consider grabbing the Xbox Game Pass Ultimate. It’s typically $15 a month, but you can get a free month when you buy this offer at StackSocial. Hurry, because the offer is currently slated to expire in three days (though it could be extended).

Despite the “Xbox” name, Game Pass Ultimate offers over 100 high-quality games on Xbox consoles — Xbox 360, Xbox One, Xbox Series X and S — as well as Windows PCs. New titles are added often so you’ll always have something new to play. This membership includes Xbox Live Gold, Games with Gold and console multiplayer, as well as access to EA Play, which offers an additional several dozen games from the Electronic Arts catalog. Free perks include in-game content and being able play games on your mobile phone and tablet from cloud (on compatible titles and devices).

There are two big things to keep in mind before you take the plunge. First off, this offer is not stackable/combinable with other deals or codes, and it’s good only for new Game Pass users (anyone with an “active/existing Xbox Game Pass Ultimate Subscription” isn’t eligible). Also, after the promotional period of two months, the subscription will continue at $15 per month unless you opt to cancel the account.
