Mega Man X2/Energen Crystal

A beautiful locale within the depths of the Mega Man world, the Energen Crystal Caves tend to be a bat infested place with wondrous gems which twinkle merrily as you dash toward victory. Beware the falling slabs of crystal, and look out for Crystal Snali's time manipulation.

Items

 * Head Upgrade
 * Heart (need Leg Upgrade)

The Head Upgrade is the reason for this stage to be the first one, because that item helps to find the other ones. Expert players can leave this stage last and start from Overdrive Ostrich's Desert Base.

Stage walkthrough
When you get to the section where there's a green ice block above you (one bound to move) and a silver ramp leading diagonally down to the right, simply run and dash down it. When you get to the bottom wall jump upwards before you get crushed by the block! Run forwards, slide down the left wall and head through the small tunnel past 3 wall clinging enemies to reach the head armor upgrade. Get it, get the extra life if you like, run back to the big gap, dash jump to the other side and wall climb to safety. Follow the ramp to the upper right (ignore the ladder), kill the 3 bats, then approach the green ice block. It will unhinge as usual, so run back to safety. You can either climb the ladder slightly, or just stand to the left of the small indentation below the ladder (it fits nicely right there).

Maverick boss: Crystal Snail
