Burst Screen 11, 12 - Floaty Bubbles

Screen 11 - The Bubbles

For hundo runners - the Rush Super Adapter cirbuit board is relatively early on this screen.

The rising and falling water here is still on cycles from all the way back when you defeated the crab midboss. Depending on your movement to this point, water height may vary.

In general, if the water is high and you can advance, you should advance.

Jet Strats

Screen 12

Have ice equipped on this screen - you can always get there quickly with L+R (reset to buster) then R.

Hold +left to walk to the ladder and then shoot ice up into the ceiling. The ice shard ricochet will kill the enemy in 2 hits. Optimally both hit on one actual shot, but if not just shoot again.

Advance to Burst Man.
