Microsoft has announced the December slate for Xbox Game Pass with several notable additions across tiers.

There are also day‑one and seasonal additions worth checking out whether you’re on Ultimate or Premium.
Here are the main Game Pass additions to watch this month with dates and membership notes. Dates are subject to change, so check Game Pass in the app or the official page for updates.

What to know
Ultimate subscribers get the most perks — including day‑one releases and cloud streaming — but the widening of some Ultimate titles to Premium makes more games accessible to a larger group of members. If you’re on the fence about upgrading, check which specific games you want to play and whether they’re arriving on your tier.
