Everyone loves a good story.

Fungus helps you bring your story to life as a game! We make it easy for you to add colourful characters and craft gripping storylines, even if you have never used Unity 3D before.

Our intuitive visual scripting lets everyone create beautiful story games - for free and with no coding! Power users can use Lua scripting to tackle bigger storytelling projects.


Fungus is a free open source project maintained by Snozbot.


We have great documentation suitable for beginners and experienced game developers alike.

The Fungus community is super friendly and helpful, we try to help everyone no matter what your experience level. 

Free & Open Source

We believe that interactive storytelling should be accessible to everyone, so Fungus is 100% free & open source. It works great with both the free and pro versions of Unity 3D.

Fungus was inspired by other great open source storytelling tools like Twine and Ren'Py.
