I heard that some dude had leaked DLC 4 Injustice. So without further a do hereis dlc leaked characters:
3. General Zod
and the fourth and final dlc character is a guest from Mortal Kombat. Scorpion! Thank You CheatCodes.Com I did not find this but if this is wrong I'm sorry but hacks are getting better by the day so maybe it is true.
If you go to the fortress of solitude with Doomsday and Regime Doomsday , Kill Superman Doomsday will take Doomsday's place its a cool Easter egg I found.
