This is basically a membership that you pay monthly to get access to all the games included in the Game Pass.

The Xbox game Pass is a kind of game subscription. You are offered a certain number of games that you can download and play at any time. Works on Xbox and pc.

The ultimate version still includes Xbox Live Gold as long as your subscription is active.

I don't know the exact cost, I think 12eur a month.
