ENTITY // High Capacity O₂ Tank
Can't Unlock the High Capacity O₂ Tank in Below Zero
Open the data box in the Twisty Bridges, roughly south to southwest of the Drop Pod and around 120m deep. The exact distance varies because the Drop Pod spawn is randomized; craft the tank at the Fabricator after retrieving the blueprint.
MODULE 08 // RECORDVERIFIED
