This is a great classic game for the Genesis and is a very close port of the arcade game. The graphics might not be quite as good as the SNES version but the music is far superior and the gameplay and animation r also much more refined and responsive. The game isn't very long, but its long enough. You can use Iron Man, Captain America, Vision (a less common Avenger) and Hawkeye, Each character has their own abilities fighting style and such. The game could have bit a little bit longer because it was a lot of fun and all. Some of the coolest parts in the game are when your character is flying through space, or over cities just like in the current movie and you gotta blast your way through hordes of enemies in pure arcade style. Great game from Data East, great game if your a fan of Marval, great game if your a fan of video games in general.
