Metroid: Fusion
银河战士：Fusion
Metroid: Fusion is a side-scrolling action-adventure game developed by Nintendo and released in 2003 for the Game Boy Advance. Players control Samus Aran as she navigates a space station infested with parasitic X organisms. The game uses linear progression through multiple sectors. Combat and platforming serve as the core mechanics. Samus employs her arm cannon for shooting and missile launches against enemies while solving environmental puzzles. As players progress, they acquire new abilities such as the Grapple Beam and Morph Ball upgrades, which grant access to previously unreachable areas. The SA-X, an AI-controlled antagonist, pursues Samus throughout the game, adding tension to exploration. The game emphasizes combat and forward progression rather than extensive backtracking across previously visited zones.
