Metroid Fusion

Metroid Fusion is a side-scrolling action-adventure game that combines exploration, combat, and progression within a structured environment. Players navigate distinct sectors, acquire new abilities, and unlock access to previously restricted areas as they advance. The game emphasizes guided objectives alongside ability-based traversal, with a focus on atmospheric tension, evolving threats, and progression through upgrades.

The game begins with Samus Aran acting as a bodyguard for the Biologic's research team on planet SR388. Eventually, a Hornoad confronts them and is killed by Samus. However, a globular yellow organism (an X) emerges from the Hornoad as it is destroyed and enters Samus's body. Feeling no initial effects, Samus continues escorting the researchers and completes the assignment. On the way back to the laboratory, however, Samus loses consciousness, and her gunship crashes into an asteroid belt. The ship's emergency systems automatically ejected Samus' escape pod, saving her from the crash, but her gunship is completely destroyed. Samus is quickly attended to by a medical crew, who discover that the creature that entered her body on SR388 was actually a parasitic organism that they soon named X. Samus Infected 2 Samus, infected by the X Parasites. The organic components of Samus's Power Suit had become so integrated with her system that it could not be removed while she was unconscious. Large portions of her infected suit had to be surgically removed, dramatically altering its appearance. However, the X in Samus's central nervous system were too embedded to be removed safely; Samus's chances of survival were lower than one percent. Metroids are the only known predator of the X; however, since Samus destroyed all the Metroids on SR388 in a previous mission, the X were able to multiply unchecked. Seeing this as the key to curing her, doctors proposed using a Metroid cell from Samus' dead Baby Metroid to make an anti-X vaccine. Apparently, the Federation had managed to preserve a cell culture from the Baby that saved Samus while she was on Zebes a second time. The serum was prepared and injected without delay, completely eradicating the X. There were, however, two side effects: Samus could no longer be hurt by normal X and could even absorb them to replenish health and ammunition, but she also inherited the Metroids' vulnerability to cold. Upon recovering, Samus is sent to investigate an explosion on the Biologic Space Laboratories research station, where the specimens from SR388 and the infected pieces of her Power Suit are being held. Once she arrives at the station, Samus immediately heads to the Quarantine Bay, where she encounters and kills a Hornoad that has been infected by an X parasite. Samus speaks with her new gunship's computer (whom she has named "Adam", as it reminds her of a former CO) and learns that the specimens brought back by the field team have become infected by the X. The computer also reveals that the X can use the DNA of its prey to create a perfect copy, meaning any organic life on the station may also be infected. SA-X 1 The SA-X. As she continues to explore the station, Samus discovers that the X have used the infected portions of her Power Suit to create a copy of Samus herself, dubbed the SA-X (or Samus Aran-X). Since the SA-X arose from Samus's fully-upgraded Power Suit, it has all of her powered-up abilities, as evidenced by it using a Power Bomb to escape the Quarantine Bay. By exploding the bomb, the SA-X also destroyed the capsules holding the X specimens, releasing them all into the station. Well into her investigation of the station, Samus stumbles upon the facility's Restricted Lab. Here, she finds dozens of infant Metroids and several more Metroids in various stages of maturity, all in stasis; these were the results of a cloning project of which Samus was not previously aware. Shortly after Samus discovers them, the SA-X attempts to destroy its predators, but its plan backfires: the Metroids break free an
