The cryptosleep casket is used to contain a humanoid or animal in a state of suspended animation.


Cryptosleep caskets can only be constructed once the Cryptosleep casket research project has been completed. Each requires Steel 180 Steel, Uranium 5 Uranium, Component 4 Components, Advanced component 1 Advanced component, 3,200 of work, and a Construction skill of 8.


A pawn can enter or be carried into a cryptosleep casket to activate cryptosleep. Inside, the occupants biological functions are suspended; they will not age biologically, and most needs and health conditions like hunger, drug addiction, and disease are suspended. However, social standing and time-sensitive mood effects do tick down while in cryptosleep. While in a casket, a colony's pawn counts as 100% of their actual wealth, but only count as 30% of a colonist when determining raid points. This means that pawns do count for determining raid size, just for less.

For colonists, simply select the colonist, right click the casket, and select "Enter cryptosleep casket". Other colonists can drag downed pawns by right clicking the pawn in question. Animals or prisoners can be put into cryptosleep caskets, but they need to be downed first. You can set an operation to apply anesthesia, which requires a unit of medicine. Alternatively, you can use violence, or, if they have a brain implant Content added by the Royalty DLC, they can also be EMPed to cause brain shock to quickly and cheaply down them.

After waking from cryptosleep, a humanoid will have cryptosleep sickness for a short time, which reduces consciousness and manipulation and causes vomiting.

In order to exit a cryptosleep casket, another pawn must be directed to open it. If no controllable pawn is available to open a casket, you are unable to do anything until a raider or another random event happens to destroy it.

When a cryptosleep casket is severely damaged[How damaged?] it will begin to spark and emit a hissing sound for ??[How long?] before exploding, dealing 10 Flame damage in a 2.66-tile radius and potentially igniting flammable pawns, buildings, and flooring in the area. For a full list of effects, see Flame.


This device can help relieve a colony during a crisis, such as an intense psychic wave or medicine shortage, by safely storing pawns until the problem is resolved. Additionally, pawns addicted to a drug will not progress through withdrawal during stasis, making the casket a handy way of saving the life of a Luciferium-user, or decrease total demand over time.

With the use of anesthetic, prisoners can also be stored temporarily to lessen the drain on colony resources while they await sale, harvesting or, if the Royalty DLC is installed, exchanged for Honor. It is also useful to save enemies/animals for recruitment and taming until an inspiration, particularly - thrumbos and enemies with high resistance.

Researching cryptosleep caskets is required to build a ship to the stars. Ancient cryptosleep caskets, from an ancient shrine, can be used before you have research; see below for details.

Comparisons to other caskets[edit]

There are three types of cryptosleep casket:

  • Casket Acquisition Placement Opening Resource Cost
    Cryptosleep casket Built Anywhere Can only be opened by a hauler, using the 'Open' designator Steel 180 + Uranium 5 + Component 4 + Advanced component 1
    Ship cryptosleep casket Built Must Connect to Ship Beam Colonist may eject self Steel 120 + Uranium 14 + Component 3 + Advanced component 3
    (+Steel 200 + Plasteel 40 + Component 3 + Advanced component 1
    per 8 caskets)
    Ancient cryptosleep casket Found in Ancient shrines Where found Can only be opened by a hauler, using the 'Open' designator None
  • Ancient cryptosleep caskets have the massive advantage of not requiring research or materials. However, they can not be built or uninstalled, which can make them very inconvenient to walk to or defend. You are also required to empty out a potentially dangerous ancient shrine, along with its current inhabitants. Cryptosleep caskets can be built anywhere.

    Ship caskets are more expensive and require significantly more research (10,800 pts more) than standard caskets, and also require a ship structural beam to attach to, increasing the cost again. However, not only are they required to build a ship, they also allow the pawn to eject themselves. This can be vital when the pawn is alone, or when there is nobody alive and mobile to release them. It also allows players to release enemies or animals at will, without pawn intervention.
