2K Games has added yet more titles to the Alpha Preview of the Xbox Game Pass, covering some of its biggest franchises.

XCOM: Enemy Within, NBA 2K16 and WWE 2K16 have all sneaked their way in to the Game Pass library, though at the time of writing we're unable to install the latter two of the trio. That could also be down to any number of things including regional rollouts or just bugs in this very early preview stage.

Here are almost 200 of the absolute BEST Black Friday deals available

Nevertheless, the latest titles from 2K join the already added Borderlands and Bioshock collection, as gradually the Game Pass library gets padded out ahead of its full launch later this year. We're still a way off the 100 titles Microsoft has promised, but we're getting slowly closer.
