Mega Man Xtreme/Flame Stag

Heart
When you start the stage, jump on the second pillar and wait there: the robot beetle will smash itself on the rock and open a new passage.

Make sure the Rapid Fire and the Auto Charge are on. After the three wall robots, climb quickly the vertical lava tube. You'll see the Heart past a pillar robot: destroy it and get the item before the lava submerges the area.

Body Upgrade
Enter the caves from the main entrance, ignore any passage that the robot beetle could have opened. From that platform, jump-dash to the right and get to Dr. Light's capsule. You'll receive the Body Upgrade.


 * "Take this Body Upgrade. This upgrade will increase your defensive ability and you'll receive less damage... Protect peace and our future!"

Dash-jump back to the previous platform.

Maverick: Zain
Zain is an optional boss: you can avoid him just by navigating this cave along its bottom.

Instead, if you want to fight him, climb up to the top of the cave. Zain is weak against the Shotgun Ice: you should not have that special weapon yet, but he's an easy enemy anyway.

Zain's sword protects him from bullets. When Zain jumps, dash under him and hit him in the back.

After you defeat Zain, leave his room and climb down the stairs. Be careful: from the ladder, jump to the right or you'll fall in the lava pit.

Continue up another lava tube and you'll eventually get to Flame Stag.

Maverick: Flame Stag
Flame Stag is weak against the Storm Tornado. Make sure the Rapid Fire is turned off.

Flame Stag's attacks:
 * Speed Burner
 * Burning dash
 * Shouryu-ken (flaming dragon punch)

The weapon obtained from Flame Stag is the Speed Burner. It will become especially useful once you get the Arm Upgrade. It is necessary to obtain several items.
