Chapter 1
After the short cut scene of Supergirl's escape of Argo City, you reach the present time with Bruce Wayne standing in a court recapping the events of Superman's downfall back in Injustice: Gods Among Us. You are then taken back in a flashback no less to several weeks before then. You see Batman and Robin heading to Arkham to stop Superman, before he created his new regime, from assassinating all the super villains in the Arkham Asylum. Cyborg is there, on Superman's side of course, to stop Batman.
After defeating Cyborg, you are able to enter the Asylum. Wonder Women is there and waiting for you at the gates of the building, the same who still pledges her loyalty to the Man of Steel. After defeating her as well, Batman takes her Lasso of Truth to find out exactly where Superman is in the Asylum. He gets the information he is looking for, along with a few selective words from Wonder Woman herself.
Once inside the Asylum, you will come to find Superman rounding up all the convicts, only to see Batman quickly interrupt. The two of then argue on the issue of whether or not executing all the inmates of the Arkham Asylum is morally just. As the arguing begins to escalate, Batman pulls out a Red Solar Grenade, a weapon to dull Superman's powers for a fair fight.
Once Superman is defeated and is brought to his knees, Batman is prepared and ready to cuff him with Kryptonite. However, before Batman can take bring him in, Robin shows up with another convict and kills him in front of Batman to prove and show his alliance with Superman and his ideals that criminals and murderers shouldn't live. Batman is then forced to fight Robin, his very own son. After defeating Robin, Superman will concede from the struggle of the day and flee from the scene.
