This is a comparison of the sprites/color palettes being used for Another Metroid 3 Port. And yes, you can play as Zero Suit Samus. Crazily enough, Samus isn't a robot. GOTTA LOVE SOME BIRD MAGIC. Ninu sen Thoha/Mawkin...
Shout out to @Orpheon on Youtube. Bird magic is their passion. Suit Abilities Power Suit - The regular Power Suit, can be upgraded. Varia Suit - Divides all damage taken by 25%, and protects Samus from the extreme heat found in Norfair and parts of Crateria. Gravity Suit - Divides all damage taken by 50%, allows Samus to move freely under water, and protects Samus from most lava. Zero Suit - Increases damage taken by 2. Consider it a hard mode unlocked for beating the game in under 2 hours. The damage reduction abilities of the other suits are still in play here, though the reduced product is still multiplied by 2.
