KIS introduces new gameplay mechanics by adding a brand new inventory system and EVA usables items as tools. You want to build a rover on Duna from scratch? Or you've forgot to attach a solar panel to the planetary station? With KIS it's not a problem!

Kerbal Inventory System (KIS)

The mod offers container parts of various size to deliver spare parts to the orbit or at the construction site.

  • Tiny containers for light-weight rockets.
  • Big containers for serious projects.
  • Mk3 containers for really big constructions ideas!

Kerbals now have own backpack to hold small items, and some of them can be equipped on the model. AR goggles? Fancy hat? Or, maybe, a completely new helmet?! It's all possible now!

With special tools (provided by the mod) kerbals now can modifying teh existing vessels by adding or removing parts. It's even possible to build a whole new vessel from scratch!

* Goggles, hats and helmets are provided by the third-party mods. E.g. "Kerbal Props".

Other useful mods for EVA

If you want doing EVA comfortably, you really should consider adding these mods as well:

How to install

  • Recommended:
    • Install and run CKAN.
    • Search for "Kerbal Inventory System" or just "KIS", then install the mod.
    • Occasionally run CKAN client to update KIS (and other mods) to the latest version.
    • If you follow this path, then all the KIS dependencies will be updated automatically. It may save you a lot of time during the update.
  • Manual:
    • Download the ZIP archive:
    • If you have an older version of the mod in your game, you must delete all the old files first! Do not just copy over, this will likely result in compatibility issues.
    • Unzip the release archive into the game's GameData folder.
      • Note, that names of the folders must be exactly like in the archive or the mod won't work.
      • The release archive contains the minimum versions of the required dependencies: ModuleManager and CommunityCatgeoryKit. If your game has better versions, do not overwrite!
    • Verify the installation: the mod's file must be located at <game root>/GameData/KIS/
  • If you don't want seeing the fun parts in your game, you can remove them:
    • Find file remove_fun_part_patch.txt in the mod's folder.
    • Rename it into remove_fun_part_patch.cfg.
    • Move it one level up in the directory structure (into the GameData folder).
    • Now the fun parts won't show up even if you update the mod.
