Suit upgrades enhance Samus's defensive capabilities and provide new movement options, allowing her to access previously unreachable areas. These are critical for progression and survival.
- Varia Suit: Your default suit provides basic protection.
- Hazard Shield: Acquired on Bryyo. Protects Samus from extreme heat and corrosive environments, allowing access to lava-filled areas.
- Gravity Suit: Acquired on Elysia. Allows Samus to move freely underwater and provides increased resistance to damage.
- Hypermode: Not a suit upgrade in the traditional sense, but a core ability gained early on. Allows Samus to channel Phazon for increased power, but at a risk of corruption.
Each suit upgrade is usually found after defeating a major boss or completing a significant planetary objective. They are essential for navigating the diverse and hazardous environments of the galaxy. Without the correct suit upgrade, certain areas will be impassable or inflict constant damage.
