Exosuit Forge

The Exosuit Forge is the station used to craft exosuits and keep them supplied with oxygen, allowing Duplicants to safely enter hazardous, unbreathable areas. Once an exosuit is filled with oxygen, it can be worn to move through dangerous regions without exposing the wearer to the surrounding atmosphere.

Its crafting recipes only appear after the required materials have been discovered. The forge has multiple suit recipes, with one additional repair material listed for each suit type. In practice, this makes it a progression building that scales from early metal suits to more advanced variants.

• A suit can be made from 300 kg of copper, aluminum, iron, cobalt, or nickel plus 2 Reed Fiber or 2 Drecko Fiber. Repairing it consumes 1 Reed Fiber or Drecko Fiber.
• A suit can also be made from 200 kg of steel plus 2 Reed Fiber or 2 Drecko Fiber. Repairing it consumes 1 Reed Fiber or Drecko Fiber.
• The lead suit recipe uses 200 kg of lead and 10 kg of Glass. Repairing it consumes 5 kg of Glass.

Because exosuits must be charged with oxygen before use, the forge is usually part of a broader suit-support setup rather than a standalone crafting station. It is most useful when paired with a reliable oxygen supply and a route that lets suited Duplicants move in and out of contaminated or otherwise lethal areas efficiently.
