Speed booster

The Speed booster is an upgrade available for Samus Aran in Metroid Fusion, Super Metroid, and Metroid: Zero Mission.

This upgrade also gives Samus the Shinespark ability, which can be used to traverse theoretically infinite vertical and horizontal distances, as well as destroy enemies. Performing this move will also allow Samus to smash through blocks that are weak to the Speed Boost. In addition, Shinespark can be performed while in Morph Ball mode.
