The Adventures of Batman & Robin is a 2D beat-'em-up game. Attacks are determined by proximity rather than button input, similar to the Shinobi series. Attacking close to an opponent results in punches or kicks, while attacking from afar results in a projectile attack. Shooting and walking at the same time is not possible. Not firing a projectile for a certain time charges up a super shot.
Being a relatively late Mega Drive game, Adventures of Batman & Robin uses a number of programming tricks to achieve graphical effects not thought possible on the console at the time, including simulate transparency (through the highlight/shadow mode), pseudo-3D flight stages and the tilting and rotating of sprites in software (unlike the hardware scaling and rotation capabilities added by the Sega Mega-CD).
