Similar to what NetherRealm Studios did with Mortal Kombat where they ported the game to the PS Vita several months following the game’s release, it looks like Injustice: Gods Among Us will get the same treatment.
While it’s not officially announced, a rating for the PS Vita version of Injustice: Gods Among Us has been found in Germany’s USK rating board. Let’s hope NetherRealm will officially confirm this in the coming weeks as a portable Injustice sounds good to me!
