Surprise: Injustice 2 is bringing burly comic book characters to the PlayStation 4 in 2017. The game – which leaked yesterday – promises to offer "all of the things that you'd expect from a sequel". That, of course, includes new fighters and environments, but Mortal Kombat developer NetherRealm Studios also promises better destruction and much more.

"We've introduced a brand new Gear System, allowing players to build their own version of Superman, their Batman, and, ultimately, their Injustice Universe," community specialist Tyler Lansdown wrote on the PlayStation Blog. Essentially, you'll get loot drops as you play, allowing you to customise your characters the way that you see fit. A neat idea – but potentially tricky to balance?

You can also expect a story mode. "When last we saw them, Superman was imprisoned in a Red Sun prison cell, while Batman was continuing the good fight against the forces that would see Superman's tyranny back in power," Lansdown continued. "Where do we go from here? And what new characters will join the fight?"
