The Metal Storage is a level 1 structure available to both the ARM and the CORE. For each Metal Storage built, the player's metal stock capacity is increased by 1000. Conversely, each Metal Storage destroyed will reduce the player's metal stock capacity by 1000, and the excess metal is lost. The building is useful in storing excess metal for later use, especially considering metal production is generally much lower than that of energy.
This will increase metal storage capacity.
