Mega Man Xtreme/Chill Penguin

Walkthrough
First of all, equip the Storm Tornado: there's no reason to leave it behind. Make those blue capsule useful and have fun with the Storm Tornado through this stage.

Leg Upgrade
Dr. Light's capsule is in the middle of the passage, and there is no way to avoid it.


 * "Take this Leg Upgrade. The upgrade will enhance your mobility on climbing the walls... This upgrade will also allow you to crush certain blocks. Your field of activities has now been expanded. Go destroy the evil, X!"

Ride Armor & Heart
When you leave the cave, a Ride Armor is in plain view. Instead of entering the next cave, walk above the hilltop. Stand on top of the stump, jump with the Ride Armor, then press up and jump off the Ride Armor: this way, you should reach the wall above the cave entrance.

Switch weapon to the Speed Burner. Shoot the first blue construct three times to reveal the Heart.

Switch back to the Storm Tornado and continue to the boss room.

Maverick: Chill Penguin
Chill Penguin is weak against the Speed Burner. Most of his attacks deflect or absorb X's shots.

Chill Penguin's attacks:
 * Shotgun Ice
 * Sliding dash
 * Ice statues
 * Snowstorm

The weapon obtained from Chill Penguin is the Shotgun Ice. It will be useful in the rematch against Zain.
