One of Samus Aran's trademark attacks. The Screw Attack upgrade is the apex in a series of jump upgrades and is found in every Metroid game except for Metroid Prime. The Screw Attack icon often serves as the logo for the Metroid series as a whole. It allows her to spin when she jumps to damage enemies. There are many less-awesome upgrades that usually come before the Screw Attack, but they're all vaguely related to Samus jumping, so they all go in this section.
||Allow Samus to jump 1.5 times as high. Found in all Metroid games. From Metroid Fusion on, getting High Jump also lets you jump while in Morph Ball mode.
It's like a normal jump, but high.
