Based on the 1995 action movie, Batman Forever is a critically panned sidescrolling beat 'em up. 2 players can take control of Batman and his circus acrobat sidekick Robin to battle Two-Face and The Riddler and other standard lackeys. It combines the Mortal Kombat engine with a generic sidescroller.
Keirden uses both of the superheroes and rolls through the game in a speedy 15 minutes.
