Super Metroid: Z-Factor is a ROM hack of the classic Super Metroid for the Super Nintendo. It reimagines the level design of planet Zebes, featuring a larger map with significantly altered room layouts while maintaining the original region structure. Although gameplay remains largely unchanged, minor ASM modifications enhance enemy dynamics and PLM interactions, encouraging exploration and allowing for limited sequence breaking.
This ROM hack of Super Metroid is a complete make over of planet Zebes level-design wise, very few rooms actually look like they used to be. The planet is a little bigger now, it still relies on the original region structure but laid out differently. The gameplay is unchanged. There are numerous small ASM changes, mainly on PLM and enemies so as to keep the player interested in exploring. Item progression and item count has been slightly altered. Sequence breaking is also possible to some extent.
