I wish I had more time to follow E3 right now, but I have to settle for the snippets that I can fit in, one of which was the upcoming game "Injustice". "Injustice" is being developed by NetherRealm Studios, the makers of the 2011 Mortal Kombat game. While the art style seems very similar to MK, "Injustice" thankfully seems to be lacking the controversial, and pretty gross, finishing moves of the MK series. From the short trailer, this game is clearly not bound to standard comics reality, as we see, among other things, Batman kicking Solomon Grundy through a building.
"Injustice" is going for the cool "let's smash everything!" persona of most fighting games. I would love another good DC hero game to rival their Arkham series, but fighting games are bottom of the barrel for story, but until that happens, I'll have to settle for this.
