Mega Man Xtreme/Computer Core revisited

Stages walkthrough
The four final stages of Hard Mode are almost identical to the previous ones in Normal Mode. Therefore, this page will just describe the differences.

Computer Core, stage 1
You will fight Geemel instead of Zain.

Computer Core, stage 2
In Easy Mode, the room with the Hadou-ken and Shouryu-ken is now empty, since you already collected those techniques.

Computer Core, stage 3
The Teleport System is different: it includes the four Mavericks introduced in the Hard Mode.

Sigma Hideout
Techno is not there anymore. Sigma is now stronger.

Extreme Mode
Once Hard Mode is cleared, Extreme Mode will unlock. In this mode, you play the whole game with the eight Mavericks at once and both Zain and Geemel. There is no plot, though: it's a mode about fighting only.
