How It Works

The Cryo Vault is built under the Misc tab and requires 120 Steel and 4 Industrial Components to construct. Once built, right-click any colonist to order them to enter, or select a pawn and right-click a baby or downed colonist to have them carry them in.

Pawns stored inside are passed into a suspended world state — they are completely frozen. No food consumption, no mood changes, no disease progression, no biological aging. They are effectively outside of time until you choose to wake them.

The vault uses a custom internal storage system rather than the vanilla cryptosleep casket container, which is what allows it to hold far more than one pawn. Eject individual pawns or groups using the Eject Pawns... button, or wake everyone at once with Eject All. Hovering over a pawn's name in the eject menu shows a live summary of their health, mood, hunger, age, injuries, and current thoughts.

The pawn limit is configurable in Options → Mod Settings → Unlimited Cryo Vault/Cyro++, with options ranging from 1 through to Unlimited.

AI Disclosure

This mod was built with the assistance of AI tools,including the Code/Edited-Description and Image used for the item and I want to be upfront about that.

The initial version was started using Copilot, which generated a significant amount of broken and hallucinated code — referencing APIs that don't exist, missing critical RimWorld-specific patterns, and producing errors that prevented the mod from loading at all.

The mod was then rebuilt from the ground up using Claude, which identified and fixed every issue Copilot introduced, rewrote the core storage system, implemented the stasis mechanics, the eject UI, the pawn limit settings, the job driver for walk-up entry, and resolved numerous compile errors caused by non-existent RimWorld APIs being suggested by Copilot.

I am not a professional programmer. The mod works well in my own testing but edge cases may exist that I haven't encountered.

Compatibility & Support

RimWorld 1.6 (Odyssey)
No known conflicts with other mods at this time.
Should be safe to add to an existing save.
Removing mid-save is not recommended if you have pawns stored inside a vault.

If something breaks, I will do my best to fix it — but please understand I am working with limited programming experience. Bug reports are welcome and appreciated, just be patient with me. Include your debug log if you can!

Note

The vault provides vacuum/decompression protection for stored pawns when playing with the Odyssey DLC. Due to RimWorld API limitations this does not show as "Airtight" on the building info screen, but the protection is active — pawns inside will not suffer decompression damage. No DLC is required to use the mod.
