Here you’ll find a list of some of Samus’s special abilities. Some of these are fairly crucial to the progression of the game, and essential if you want to get 100% powerups, so practice some of these until you’re a pro. Here is a list of Samus’s special abilities, and how you can pull them off.
Shinespark
How to do it: Speed Boost until you are blue, and then press down on the control pad. Samus will blink for a few seconds. At this time, press the jump button to launch yourself straight upwards. Conversely, you can also launch yourself to the right or left by pressing the direction and then jump.
Usefulness: Extremely. Master this, for there are several powerups that are unobtainable without the proper usage of Shinesparking.
Wall Jump
How to do it: Jump towards a wall, making sure that Samus is spinning in the air. When you connect with the wall, immediately press the opposite direction of the wall you touched and Samus will launch herself in that direction. You have to press firmly either to the right or left – if you’re too soft or pressing more on the up button than the direction button, you’ll fall.
Usefulness: Depends. The wall jumps are more limited in Fusion than Super Metroid, meaning that you can’t wall jump upwards and then jump again off the same wall. You’ll be propelled to either direction fairly strongly, so wall jumping here won’t be as crucial unless you’re speedrunning. Still, there are some Expansions you can grab earlier than intended by knowing how to perform this technique.
