Energy Tank

An Energy Tank upgrade in Echoes

The Energy Tank is a common Suit Expansion in the Metroid series, featured in every Metroid game to date. The Energy Tank is used to increase Samus's maximum energy by 100 units (with the exception of Hard Mode in Metroid: Zero Mission, where each Tank increases Energy by 50). They also refill Samus's energy to full upon acquisition. Extra Energy Tanks are represented by small boxes near the top of the HUD. These, like other expansions, are not required to progress through the games' plots, thus creating two challenges: completing the game with all the Energy Tanks acquired, and completing the game with the least amount of Tanks possible acquired.

Ridley	No items are needed	After defeating Ridley, Samus must travel to a corridor with pipes that send out bugs, then lay a Morph Ball Bomb near the entrance of the corridor to access a network of tunnels; the Tank is at the end of the tunnel.
