Mega Man X4 Walkthrough

Memorial Hall: Colonel
If you're playing as Zero, this is just a cinema scene here. Zero and Colonel have an argument, and Iris soon comes to break up the fracas. If you play as X, this is a short stage with a minor boss battle. Ultimate Armor makes this battle MUCH easier!

Part 2: Sigma
Note: Best. Sigma. Final. Battle. Music. Ever!
