In X-men 2: Clone Wars, the alien race Phalanx invade the earth and the X-men and some X-women try to stop them.

You get to choose which X-man to play every stage as. Most of the time Nightcrawler is used because he has the highest movement speed. Second in command is Wolverine because he has the second highest speed and also deals a ton of damage.

The game is unique in the regard that it starts as soon as you power on your console. No SEGA logo, no title screen, you don't get to choose a character. Normally the game pseudorandomly gives you Beast, but changing the types of controllers (3- or 6-button) throws off the start-up timing enough that a faster character can be gotten.

This movie features some nifty tricks and shortcuts, such as abusing Nightcrawler's teleport, attacking through floors, and going extra fast in the falling levels. This game has had several attempts, but this is the first published version.
