Splitkick: Injustice is a serious fighting game. Without the Mortal Kombat name to hold it back, NetherRealm was free to experiment. You can now hold back to block. Frame data is exposed in-game in the move list. You can tag moves to leave their input instructions displayed on the screen even as you fight. There is an online mode for practicing against a human, to train against a friend with unlimited life bars and no time limit. Online hotfix patches can be instantly delivered to patch infinite combos. There are a ton of tools here to better your game, superior to almost any other fighting game on the market.
