Energy Tanks are crucial for survival, especially in the later stages of the game. Each Energy Tank adds 100 units to your maximum energy, effectively giving you an extra life bar. Collecting all of them will make even the toughest Metroid encounters manageable.
Locations: Similar to Missile Expansions, Energy Tanks are hidden throughout SR388. They are often found in more challenging-to-reach locations, sometimes requiring a combination of abilities like the Spider Ball and Space Jump. Prioritize finding these, especially if you're struggling with a particular area or boss. They are usually found in dedicated, small chambers.
