Aeion Tank

An Aeion Tank is a new expansion in Metroid: Samus Returns. With each Aeion Tank, Samus's Aeion Gauge is slightly increased, allowing her to store more Aeion energy. The tanks appear as floating yellow cubes with a pattern on each face, and each tank is positioned above a pedestal. Samus can obtain 15 Aeion Tanks in the game, in all areas of SR388 except for Area 8.
