This is a GBC-exclusive game based on the popular American comic book "X-MEN," published by Success. The genre is 2D fighting. The company also released two PS versions of 3D fighting games with the same title. Playtime is about 20 minutes if you're just trying to unlock the hidden characters. Since it's difficult to use as a versus tool on a GB game, and the controls are... well, that's about it. Most GB fighting games are pretty good, with light hits and a sense of exhilaration, but this one is a bit different. You might find it easier to think of it as a fighting game from the FC era rather than a modern fighting game. There is no knockback in this game, so a match ends by just repeatedly pressing the fast A button punch attack. Or rather, that's basically all there is to it. FIGHT! Approach! Crouch punch spam! WIN! It's like that. There are special moves and super special moves, but they're difficult to execute, their power is negligible, or they're just for show. In addition, some characters can unleash special move-equivalent projectiles by holding down a button... yeah. There are five selectable modes: Story, Communication Battle, Arcade, Survival, and Training. That's a sufficient number of modes for a console game, but it feels a bit lacking for a GB game where it's difficult to play against others. To be honest, I wish there was at least one bonus mode... It's a game with GB-like quality, but it's just... not quite there, which is the overall impression.
