Diving in the Underdust holds many dangers that you should be aware of at all times. Not only do you have to refer to your health and stamina like in most survival games, but you’ll also have to pay attention to your hydration and oxygen levels. The dust is too toxic to inhale, so any attempt to explore the world beneath the deposited dust requires oxygen. But with a small tank to work with for beginners, you’ll want to get your hands on a larger oxygen tank as soon as possible to continue your search for the secrets of humanity after it’s gone. This is Vincent’s guide to where to find the medium oxygen tank in Forever Skies.
Medium Oxygen Tank Location Guide
In Forever Skies, you may feel like you’re on a very limited timer to explore due to your oxygen tank. Because of this, players will want to update this as soon as possible. But while you can’t just build a bigger tank, you can find the plans to build one relatively early in your game. The medium oxygen tank can actually be found in your first real Underdust mission. This is when you research the lab in the Underdust. You will also find the virus analyzer inside the lab which can help you in your survival against the elements.
Luckily, the area you need to go to for the Oxygen Tank is located quite close to your Airbase elevator. If you ever get a bit lost and need to replenish your oxygen between runs, be sure to refer to the white arrows on the ground to find your base. From your base, immediately turn left and follow the path, ignoring the staircase and the door in front of you. Continue left until you reach another opening where there is an oxygen stand which requires a Crystal battery to be used at its center. Ignore this and go to the wooden beams creating a walkable platform located behind the dust daisy. Crouch under the metal beams and follow the ladder-like platforms until you have to jump down and reach the end of the platform area.
From there, you will find a half-open door, located on your left. Head inside to find a corpse with two medium oxygen tanks and a crystal battery on his body. You need to scan the tank for its blueprints which can then be searched further back at your base for a larger oxygen tank to take with you on each trip to the Underdust.
