Xbox Game Pass is basically a Netflix-like subscription service, you just replace films and TV shows with video games. Upon subscribing you will access to a library of 100+ games that you will be able to download and play with no limit on time. This service is available now for Xbox Live Gold Subscribers and will be launching for everyone else on June 1st.
£8 per month will net you unlimited access to a wide variety of titles that will cycle in and out each month as well as 20% off such titles that are currently in rotation. Games include Halo 5: Guardians, Gears Of War 1-3 + Ultimate, Payday 2, Mad Max, Borderlands, Bioshock and much more. If you don’t quite want to spend the money straight away you can jump in with a 14-day free trial!
Remember you only have access to the titles and discounts if you have an active subscription, if you cancel you will lose access to the titles unless you purchased them.
