Ais up with a few letters and numbers with a planet backdrop. S A R 0 1 0 1 is currently all that's showing, presumably with more cropping up as time goes by.
It's unknown if whatever this is will come to PC of course, but let's hope it does. The Facebook link for the teaser has "Square Enix New Project NEXT 2015.04.13" on it. Wein the cyberpunk glow of Deus Ex: Mankind Divided regardless, which hasn't been dated yet.
