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 Component, Advanced component 1 Advanced component, 3,200 of work, and a Construction skill of 8.


During cryptosleep, the occupants biological functions are suspended and they will not age biologically, only chronologically. The pawns stats and status effects will similarly be frozen (this is not completely true; some effects, such as mood and social, do tick down while in cryptosleep) - their hunger will not decrease, any injuries won't progress and any drug doses will remain the same. The player may select a cryptosleep casket and look at the inspect pane to see if it is empty or occupied.

To have a colonist enter a cryptosleep casket, simply select the colonist, then right-click a cryptosleep casket, and choose "Enter cryptosleep casket". Alternatively, if the colonist is downed, another colonist can be ordered to carry the downed pawn to the casket.

Animals or prisoners can be put into cryptosleep caskets, but they need to be downed first. This can be done violently, by applying anesthesia followed by manually directing a colonist to carry them inside 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.

When a cryptosleep casket is severely damaged it will spark briefly then explode. Nearby flammables may catch fire.


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 avoiding withdrawal-induced mental breaks in the event of drug shortages - this technique can be used to save 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.

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

Comparisons to other caskets

There are three types of cryptosleep casket: the standard (this article), ship and ancient. Standard caskets can be built anywhere but require a significant resource and research investment and occupants can only be released by another pawn.

Ship caskets are more expensive and require significantly more research (10,800 pts more) than regular caskets, and also require a ship structural beam to attach to, increasing the cost again (though one structural beam has room for up to 8 caskets, depending on positioning). They can be placed anywhere that a beam can be constructed and 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.

Ancient caskets are similar to standard ones but cannot be constructed. They are often found pre-installed in ancient shrines, but they cannot be moved from where they are. This can make for inopportune positioning or can require additional investment to protect them. Additionally, the ancient shrine must first be cleared of enemies, occasionally including the current inhabitants of the caskets.
