Carrying multiple oxygen tanks will increase your survivable exposure time in hostile environments.

― PDA, Dialogue

The Standard O₂ Tank is a crafted piece of Equipment which boosts the player's Oxygen supply by 30 units. The player has an equipment slot just for the Standard O₂ Tank, freeing up space in their Inventory.

The player can carry multiple Standard O₂ Tanks at a time in their inventory. Additional Standard O₂ Tanks carried in the player's inventory will extend your oxygen supply, but will take up four slots (2x2) in the player's Inventory and slow the player down.
