Astroneer Wiki

Hello all editors and users of the Astroneer Wiki! We are in the process of updating and switching over to use the new Fandom Desktop skin on the wiki. There will be many changes over the coming days, but the main goal is to keep the wiki feeling the same, as much as we can! If you notice any issues once the swap is made, please post them to the Admin Noticeboard so we can address it right away. We are also going to be completing the update to the Astroneer Wiki:Style guide, so there is a more up to date guide on how to style the wiki going forward.

Tier Extra Large
Group Item
Type Base Building
Crafted at Large Printer
Recipe 1x Clay

The PUM-KN Shelter is a base building item in Astroneer and central point of permanent bases. It is a reward from the final stage of the EXO Biofuel Obtainment Operation, which gives the player two small boxes and unlocks the blueprint in a Large Printer. When unboxed it will set up and turn the surrounding Terrain into a blackish-gray soil that is only removable with a Drill or Drill Mod.


The player receives two small boxes containing the PUM-KN Shelter when completing the Noxothane stage of the EXO Biofuel Obtainment Operation event, or by obtaining 5000 points in the EXO F.A.R.M event. It is also craftable in a Large Printer once either of these goals has been met.

The PUM-KN Shelter is the central part of a players base:

  • The game saves each time the PUM-KN Shelter is entered
  • A respawn point in case of death
  • An infinite source of Oxygen and Power
  • Power Production Rate: 1 U/s
  • Can be blown up using Dynamite and will turn into Spookysquash Samples and Seeds.
  • Can be used as a source for infinite soil. The shelter takes about 2 soil canisters to craft, and will generate about 4 soil canisters of soil.

The PUM-KN Shelter has two Tier-1 slots on its side to attach up to two items, as well as four power connectors to expand bases outwards


  • PUM-KN Shelters are mainly cosmetic, and act the exact same as a normal Shelter:
    • PUM-KN Shelters will provide the player with power and oxygen, similar to a normal Shelter, even though there is no indication of power or oxygen production.
    • The PUM-KN Shelter cannot be moved or packaged with a Packager after it has been placed.
  • When printing a PUM-KN Shelter, they will be printed into large crates. Small crates are only given as a reward for the event, due to the size of the EXO Request Platform rocket.
  • PUM-KN Shelters are accessible earlier compared to the regular Shelter, only requiring a Chemistry Lab to craft Plastic instead of an Atmospheric Condenser to get Silicone.
  • When deployed hard soil generates under the shelter.
  • Blowing up the shelter with Dynamite produces Sturdysquash Samples and seeds, with a chance of obtaining Spookysquash seeds as well.
