The plot of Injustice 2 begins with the planet once again unable to enjoy the established truce. A group of antagonists led by Gorilla Grodd decides to take advantage of the fact that the light side of the heroes has been partially destroyed by an internal conflict. The fight with Grodd and his assistants is just the beginning. It turns out that the world is threatened by someone much worse Brainiac. His arrival means that Batman and Superman will have to join forces. Many elements of the gameplay are taken from the first part, for example, interaction with the elements of the environment available for use during the battle but now many attacks of this type can be temporarily blocked, multi-level boards or a special indicator that allows you to enter a state, significantly increases the combat potential.
