A fighting game with heroes from two different worlds with well-known characters from the Mortal Kombat world and also with comic book characters such as Superman, Batman, or Joker. This part returns to the Mortal Kombat II legacy in terms of gameplay, especially in the fighting style. It should be smoother, the blows should follow in an uninterrupted series of actions, the combos should be chained and connected.

You will also be able to throw opponents through walls and in some arenas even send them free-falling to lower floors. Your character will jump after their opponent and a fight will ensue in the air. Other times, you will manage to catch your opponent and start a short-range fight, which will be fatal. The absolute climax will be a short mini-game. This is a form of ultimate attack, different for each hero.

The individual characters are distinguished by their special abilities. These are pretty much exactly what we would expect from the characters - Superman flies and fries opponents, Batman focuses more on brute strength and martial arts, Flash lives up to his name with many lightning attacks, Scorpion's spear attack returns, Sub-zero's ice tricks and Sona's poisonous kiss. Each special move also has its "PRO" variant, which requires good timing and skillful fingers to trigger. And finally, the famous fatal attacks will not be missing.
