The Ultra High Capacity Tank is a piece of equipment and an upgrade to the High Capacity O₂ Tank. It can be crafted at the Modification Station. It boosts the player's Oxygen supply by 180 units, increasing it to a total of 225 O₂.

The player must equip the Ultra High Capacity Tank in the tank slot of the Paperdoll UI in order to benefit from it. While not equipped, it takes up nine slots (3×3) in the inventory.

Equipping an Ultra High Capacity Tank incurs a movement penalty of 0.60 m/s underwater and 0.78 m/s on the surface. This is also the only tank that incurs a movement penalty for each one held in inventory: 1.21 m/s underwater and 1.57 m/s on the surface.

Recipe[]

The blueprint for this item is unlocked by scanning Sea Monkey Nests located in the Lilypads Crevice and Arctic Kelp Caves. It is crafted in the Modification Station.
