Xbox Game Pass Ultimate is the combination of two current programs: Xbox Game Pass and Xbox Live Gold. Subscribers to Ultimate will have access to both for one monthly subscription cost instead of two separate ones. Additionally, the newer Xbox Game Pass for PC subscription is also included with Game Pass Ultimate.
Xbox Game Pass is Microsoft’s subscription service that offers complete access to a huge library of games covering both Xbox One and backwards compatible titles. You can download these to your console to play in full for as long as you’re a paying subscriber or the games in question remain in the Game Pass library.
Besides combining all of those services into one monthly subscription, Xbox Game Pass Ultimate adds Microsoft’s cloud gaming feature, formerly called Project xCloud. It lets you play the service’s games on your Android phone, streamed from Microsoft’s servers. It’s one of the biggest draws of the Ultimate game pass, even if the service is still in beta.
