In Metroid II: Return of Samus (1991) and its 3DS remake Metroid: Samus Returns (2017), Samus travels to the planet SR388 on a mission to eradicate the parasitic Metroid species. Equipped with her adaptable Power Suit, she navigates dangerous subterranean environments to eliminate the Metroid threat. These specific titles are pivotal to her character arc, establishing her relationship with the last remaining Metroid hatchling.
The Game Boy release of
Metroid II: Return of Samus (1991), which also saw a
Metroid 2 Return of Samus [Player's Choice] (1991) reissue, significantly expanded the protagonist's arsenal. This title introduced iconic gear such as the Spring Ball, Spider Ball, and Plasma Beam, which became staples of her subsequent adventures. The game's design focused on a non-linear progression tracked by a locator counter, a mechanical departure from her debut outing.
Decades later, the reimagining
Metroid Samus Returns (2017), alongside its
Metroid Samus Returns [Special Edition] (2017) release, modernized her movement and combat capabilities. Developed by MercurySteam and Nintendo, this version equipped her with a 360-degree free-aiming system and a melee counter-attack, drastically altering her defensive options. It also introduced Aeion abilities, granting her temporary powers like scan pulses and protective shields. These gameplay evolutions across both the 1991 original and the 2017 remake redefined how players control the bounty hunter, cementing her legacy in the action-adventure genre.
