Samus is far from the “all brawn, no brains” type of warrior. She’s not afraid of looking silly to get the job done, even if that means rolling into a sphere no bigger than a soccer ball. It’s a good thing, because the Morph Ball is easily one of the most useful tools in Samus’ tool belt, and it receives its own upgrades that increase its usefulness even further. Read on for a description of each upgrade you can find for the Morph Ball.
Morph Ball
Nearly always Samus’ first Power Suit upgrade, the Morph Ball allows her to roll into a compact sphere shape, which grants her access to holes and narrow passages. The Morph Ball is undoubtedly one of the most useful upgrades in the game. While new upgrades replace old ones, the Morph Ball is handy from the moment you get it until the end of the game.
Spider Ball
It becomes clear early on that one of the Morph Ball’s biggest weaknesses is its lack of verticality. This upgrade fixes that. While using the Spider Ball, Samus can roll up walls and across ceilings effortlessly—albeit, a little on the slow side. With this upgrade in hand, there are really only two things that can keep her from going anywhere she wants: slick yellow goo-covered walls and natural spike formations that bungle of her path. Beyond those, the sky is very nearly the limit.
Spring Ball
The Spring Ball serves more as a quality-of-life upgrade than one that’s wholly necessary. It becomes obvious while using the Morph Ball that it’s not the most practical mode of transportation; you’ll likely swap in and out of ball form for the sake of expediency. The Spring Ball helps reduce that need by allowing you to jump over small hurdles and dodge enemies with more ease. It doesn’t help you solve many puzzles, but you’ll undoubtedly come to embrace its usefulness.
