Buy The Hyper Slider

(This is really here so someone clicking "Next" sees it)

After Duo, the shop expands. Menu to the globe at the bottom of stage select to go back to the first 4 and the shop.

In Any%, go all the way to the right and buy the Hyper Slider and get out (Triangle cancels out of the "Buy" menu on the US Playstation release, Circle cancels on Legacy Collection 2. There are region differences on Playstation 1 for which button does what).

Strats from this point on assume you have the hyper slider, and not having it may alter the viability of sliding strats.

I want to say 40 bolts buys the Quick Charge and Stage Exit items as well.

Buster Only must eventually purchase the Arrow Shot.

Other interesting items include the Energy Saver, which is expensive but allows for more weapon usage (like Astro Crush). It is no longer collected for any% because it takes more time to collect the bolts than the extra energy saves., but there is no reason to specifically not collect it.

Good luck Mega Man
