If you're looking for a free Xbox Game Pass Ultimate code, you might be in luck! Walmart Plus is giving away two free months of Xbox Game Pass Ultimate (in the U.S.), and there's a free 30-day trial for Walmart Plus on its website.
The Game Pass code is a limited-time offer that appears to be accessible to all Walmart Plus members, although the small print mentions that it's for new Xbox Game Pass members only, and there's a limit of one code per-account.
Bizarrely, Xbox Game Pass Ultimate is currently giving away 45 days of Walmart Plus as an Xbox Game Pass Perk as well, although as per the rules outlined above, you have to be a new subscriber to actually use the free Game Pass code that Walmart Plus is giving away... it's all a bit confusing!
Basically, this is a bit of a pointless offer if you're already subscribed to Xbox Game Pass, but if you're either new to the service or you've got a friend who might like to try it, it's worth at least claiming your free code while you can.
