Game Overview

Metroid Fusion Debug is basically the GBA classic with its guts spilled out—like finding a secret dev terminal hidden in the BSL station. You can warp anywhere, mess with enemy spawns, or straight-up break sequences in ways that’d make the original devs sweat. It’s chaotic, but in that fun "what happens if I do this?" way.

Speedrunners will lose hours hunting for new skips, while regular fans get to poke at unfinished assets and weird glitches (hello, floating Samus). The controls take some getting used to—hold Select to fly through walls, pray you don’t soft-lock—but it’s worth it for the sheer novelty. Just don’t expect it to replace the real thing. This is strictly for people who’ve 100%’d Fusion and still want more.

Fair warning: you will accidentally trap yourself in a room with no escape. Consider it part of the charm.
