This sequel augments the style and gameplay of the 2000 PlayStation original with more characters, new arenas, and graphical enhancements. Gamers can now enter the ring as Rogue, Nightcrawler, Havok, or other new characters in addition to Wolverine, Storm, Mystique, Magneto, and the mutant heroes and villains featured in the first game. Each character has different powers and attacks based on the Marvel Comics X-Men universe. Four different game modes are available, including the straightforward "arcade" and "versus" modes as well as a "survival" challenge and an "academy training" session taught by Professor X himself.
