It's been a while since we heard anything about Injustice 2, but more information could be coming this May.
On the official Injustice 2 Facebook page a date of May 16, 2017, has been uploaded without any other information. This could be a release date or a grand reveal for new characters, stages, or story details. Hopefully, it's an official release date.
Injustice 2 will launch for Xbox One, PS4, Andriod, and iOS in 2017.
