Lightweight High Capacity Tank

The Plasteel Tank is an piece of upgrade to the regular tank. It is crafted by using the Workbench, which boosts the player's oxygen supply by 30 seconds and lower the total weight that increases the player's swimming speed.

The player can carry multiple tanks at a time to further increase their oxygen capacity (but lowering space for other things). The Plasteel Tank also take up four slots in the player's inventory.

While each Plasteel Tank adds to oxygen, it also adds to your current weight, therefore decreasing the player's swimming speed.
