The Stillsuit is a piece of equipment crafted using the Fabricator. It takes up four slots (2x2) in the player's inventory. The Stillsuit's blueprint can be acquired from data boxes.


The Stillsuit is mainly white in colour, with dark grey patches on the shoulders and around the legs, a network of orange coloured pipes span the exterior of the suit.


The Stillsuit conserves and filters the player's bodily fluids, resulting in drinkable Reclaimed Water being added to the inventory, assuming there is space for it. Drinking Reclaimed Water restores 20 H2O points at a cost of -3 Food. The Stillsuit produces Reclaimed Water at a fixed rate of two per day, with a small item popup appearing whenever it does so.

The Stillsuit cannot support the player's water needs single-handedly, as the player loses water at a rate far higher than 40 per in-game day. It does prolong the player's survival in instances where they do not have easy access to water, and can be helpful on long journeys. It is important to have access to food if using Reclaimed Water to supplement water supplies, as otherwise the food penalty can easily result in the player starving to death.

Data Bank Entry


The industry standard stillsuit is designed to minimize water loss while exploring hostile environments, by filtering and recycling bodily fluids.

- Reclaimed water is stored in containers for later consumption, normal production rate is 2 bottles per day
- Filters contaminants from no less than 4 different bodily excretions
- Blood and sweat may be effectively processed, upgrade to Mk.II to make the most of tears
- Onboard flavor neutralizer can be activated at startup (flavor neutralizer not included on all models)

  • The name and function comes from Frank Herbert's 1965 novel Dune. The stillsuit is the technology of inhabitants of an arid desert planet who use the suit to desalinate and reclaim body moisture and even process waste.
  • Previously, the player had to use the Modification Station to upgrade the dive suit into the Stillsuit.
