X-Men 2: Clone Wars/Siberia

This segment consists of only one stage. Siberia is covered in snow, and acts as a short introduction to the game. The level is controlled by anti-mutant tanks and Hand Ninjas. You do not get to pick your character for this level, as it starts immediately upon booting up the game. The character you get for this level is random, so you can keep resetting until you get one you want to play as.
