The following is the “Beta 1” build of Zoo Tycoon, developed by Blue Fang Games and published by Microsoft Game Studios. The titlescreen and disc art both list this build as


  • The installer is extremely early and doesn’t feature the game’s title.
  • Install folder contains multiple “test” zoo map files.
  • Game assets aren’t compressed like the retail builds, but are instead just in zip files.
  • Contains developer mode.
