Things You'll Need
Instructions
Morph-ball bomb the lower-left area of the room after defeating Kraid, then go into the next room. Collect the Speed Booster upgrade.
Find an area that has a vertical slope and enough room to charge Samus' Speed Boost ability. (Several areas like this can be found throughout the game.)
Charge your Speed Boost ability by holding left or right until Samus begins to glow, then press down to store her charge. Samus will glow red.
Make Samus jump (while glowing) and hold any direction other than down. Samus will begin shinesparking.
Aim Samus' shinespark at a vertical slope before it ends. Samus will continue running and quickly regain her Speed Boost charge. Press down again to store the charge. You can continue shinesparking in this fashion so long as a slope is available.
