List of fangames

From KeenWiki
Jump to navigation Jump to search

This is meant to be a constantly-updated list of Keen-related fangames that were:

  • Actually released in some form (either full or demo)
  • Not made by modifying the original games (some of the best fangames are actually "mods". To see a list of them, go to Vorticon Mods and Galaxy Mods).

Information compiled from CC314, Beyond the Pogo, Bipship and the forums.

Many of these games require cncs232.dll to play.


  • CNC = Click & Create
  • CTF = Clickteam Fusion
  • DPMI = DOS Protected Mode Interface
  • GBA = Game Boy Advance
  • KNP = Klik & Play
  • MMF = Multimedia Fusion
  • TGF = The Games Factory
  • Please click on the triangles to sort by different categories. i.e. if you click first on "Creator(s)" then on "Created with", you will get a list that is sorted by which tool or engine was used, and further sorted by creator name. Refresh the page to reset all sort settings.
  • Only the newest version of each game is listed in the Download column; additional versions may be found on their respective wiki pages.
  • Dates format: year-month-day (the release date is always for the first version of the game if known)
  • Real name of creator listed first, if available, then (nickname in brackets)

For a pictorial view, see List of fangames (pictorial) instead.
