Ultra High Capacity Tank (Subnautica)

The High Capacity Tank is a piece of equipment and an upgrade to the regular tank. It is crafted by using the workbench.

It boosts the player's oxygen supply by 60 seconds. This is twice as much as a regular tank.

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

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