Before venturing deep into the dust, you'll need a reliable oxygen supply. Your first task is to craft an Oxygen Tank. This item is crucial for extending your time in dust zones. The crafting recipe will be available at your base's crafting bench. You'll typically need materials such as Empty Gas Cylinders, Rubber Hoses, and Scrap Metal. These can often be found in the immediate vicinity of your base or by dismantling certain environmental objects.
Once crafted, equip the Oxygen Tank in your inventory. It will automatically provide oxygen when you enter a dust zone. Keep an eye on its durability and refill it at your base or with oxygen capsules found in the field. Without an Oxygen Tank, your time in the dust will be severely limited, making objectives nearly impossible to complete. This step emphasizes the importance of specialized gear for specific environments.
