X-Men: Mutant Wars 2000 By: ACTIVISION

Overview:

The war Magneto predicted has finally come. You are an X-man in the middle of the Mutant Wars. In fact, you are all the X-men.
This game isn't very hard. Fight as Wolverine, Cyclops, Storm, Gambit, and Iceman. Each character has his/her mutant power you can use. Cyclops has his energy beams. Wolverine has claws and a healing factor. Storm can control the weather and fly. Gambit throws exploding playing cards. Iceman, you guessed it, can control ice. You cannot change your character in game.
X-Men: Mutant Wars has decent GBC graphics, which means that you can tell each mutant apart, but the sound quality isn't all that great, it is basically just noise.

Directions:

In this single player game, guide your team through each level and defeat each level's "big boss". As you go through each level, look for health bonuses and keys to use to get to the boss. There is only one way to find items, and that is when you walk the the paths, you come to a break in between walls or grass. Press the down button to get on a new path, where an item will appear at the end of the path. But it wouldn't be a fighting game without enemy resistance. Robots and mutant drones will guard each level. There are two different types of robots: land bots that can not fly and aerial bots that (you guessed it) fight in the air. Use long distance attacks on the aerial bots and long distance or hand-to-hand combat on mutants and robots that do not fly.
To perform your mutant power press B.
To perform an aerial attack press A and then B.
To perform an upward thrust press UP directional + B.
