Microsoft has expanded the availability of its 'Xbox Game Pass' pre-release test to a wider range of Xbox Insiders today, providing access to a library of Xbox One and Xbox 360 titles. This is ahead of the public launch of the subscription-based game distribution service, planned for later this spring.

For those enrolled in Ring 3, the Xbox Game Pass Alpha Preview Test Catalog is now available on your Xbox One console. This will provide unlimited access to 28 titles – only a fraction of the 100+ games promised for the public release. For those eligible for Xbox Game Pass Preview, the catalog can now be accessed via the following steps.

Open up the Xbox Insider Hub application. Navigate to Insider content. Select Xbox Game Pass Preview. Follow the on-screen steps to enroll in the trial service.

Those on Alpha and Beta Preview rings can still access this collection, until the trial period expires on April 28, 2017. We can only assume that Preview Ring 4 will also be gaining access over the coming fortnight before the trial concludes.

For those outside of the Xbox Insider program, an official rollout will occur later this spring for all Xbox One users. Priced at $9.99 per month, subscribers will gain access to constantly growing library of Xbox One and Xbox 360 titles for the duration of their subscription.
