    This whole series is very easy.

    1. Don't die. If you die, the counter is reset.
    2. Stay on an extreme world. How to check for extreme worlds? Your hazard protection should say EXTREME, the world's weather information should be in red when you first land, there should be storms, whatever chromatic metal it has should be Activated (Activated Copper, etc.)
    3. Build any shelter, preferably a completely closed one.
    4. Stay there, away from the door.
    5. Keep the game in that state. Go to work, go to sleep, or something, until 32 SOLS (in-game equivalent to Earth day) passes.

    The hard part of this achievement is the boredom. Building in a storm isn't much fun. You can't really hunt for stuff (except storm crystals) without burning through all the ion batteries or dioxites. Poor visibility has also claimed many travellers' lives. Life on an extreme world sucks, but you can do it.

    Just 32 SOLS!

    OarfThis has been patched with the voyager update, you cant sit in bases or underground anymore.

    But it works when you get the Weather upgrade for one of your vehicles (except minotraur)
    And you do not have to refill the vehicle weather mods, so you can afk in the vehicle

    Like I did in November 2025.

    In difficulty, remove damage from weather/elements.

    Then, simply being on a very extreme planet doesn't count; not all planets do. I did it on an ice planet with many storms and no sentinels.

    I simply stayed on the ground, waiting or managing my inventory, looking for a safe place where I wouldn't be killed by animals or sentinels.

    Dig a hole in the ground doesn't count, nor does going into a shelter or your ship. Some exoships do count.
