The Screw Attack is an iconic upgrade featured in Metroid II: Return of Samus and Super Metroid, as well as the homebrew title Super Metroid Darkholme Hospital. When acquired, it surrounds Samus Aran with a high-energy barrier during somersault jumps, turning her body into a lethal weapon that can tear through enemies and certain obstacles. It serves as both an offensive maneuver and a traversal tool in these games.
Within the progression loop of
Metroid II: Return of Samus (1992), players discover this ability hidden deep within the labyrinthine tunnels of planet SR388. It fundamentally alters the late-game pacing, granting invincibility against most minor hazards and streamlining the eradication of the remaining Metroid mutations.
In
Super Metroid (1994), the upgrade is guarded by the Golden Torizo boss in the lower regions of Norfair. Once obtained, it synergizes with the Space Jump, enabling continuous, devastating aerial movement. This iteration introduces specialized environmental interactions, as players must use the charge to shatter specific metallic blocks to access the final areas of Zebes.
The item's utility inspired early fan creators, leading to its inclusion in the homebrew title Super Metroid Darkholme Hospital (1990), where its destructive physics were repurposed for navigating a highly customized, non-traditional map layout.
Beyond its functional utility, the item is represented in-game by a distinct, rotating icon resembling a stylized letter "S." This emblem, typically held by Chozo statues, eventually transcended its role as an in-game collectible to become the official logo for the broader franchise's branding and merchandise.
