Another live event demonstration, another trailer! NetherRealm Studios are taking the heroes and villains of the DC Universe to the Tokyo Game Show, where Japan will get a first-hand look at the superhuman action of the 2013 console fighter.

Batman lurks the rooftops of Gotham City in a trailer that keeps the ominous plot vague, teasing only the tiniest hint of the rift that will bring him into conflict with Superman and the other heroes turned threat.

The action stays primarily focused on the much talked about gameplay that has many predicting another run at the tournament scene for the Mortal Kombat developer. Characters do battle in an all-new engine, featuring NetherRealm's first use of the back to block convention, more standard character-specific special attacks, and extensive environmental interaction. Wonder Woman, Catwoman and Nightwing are among the many, demonstrating their super-moves and more.

Injustice: Gods Among Us will feature a packed cast of DC Comics heroes and villains, coming to the PlayStation 3, Xbox 360 and Nintendo Wii U some time in 2013. The game will be on show September 21 - 23 at the Tokyo Game Show, before Injustice makes its way to Australia, where Ed Boon will be guest of honor at the October EB Games Expo [full story].

Update: The Verge are reporting the TGS announcement of an Injustice: Gods Among Us global release for April 2013. When the date arrives it will have been exactly two years since the release of Mortal Kombat.
