I’m guessing it didn’t sell too well as a Windows Store PC/XBox exclusive, here is the Steam page for it. It looks like it have a Direct X 11 version as well for those of us who don’t want to deal with Windows 10.
Unfortunately the only thing that’s enticing about Windows 10 is Direct X 12 which handles AMD cards with amazing results. Sadly all the other junk they’re pushing is still keeping me from wanting to upgrade anytime soon. Not that it matters, I’ll probably grab Quantum Break when it goes on a sale. I don’t feel like purchasing Microsoft sloppy seconds at top dollar, hell I haven’t even purchased the new Tomb Raider yet…
