If you’ve spent any time on Steam for the past decade or so you’ll likely be very familiar with Overgrowth, a third person parkour and martial arts game that spent nine years in Early Access, acting as a pioneer for the system that many games still use today.

Overgrowth did eventually launch out of Early Access in October 2017 and it’s been worked on since then, and now indie developer Wolfire Games has announced the latest move in this game’s journey by opening it up to the public by going open source.

The game will exist as an open source title with the full project files, engine, scripts and shaders available on GitHub for anyone to use under the Apache License Version 2.0. Those thinking about making their own projects should read the details of this licence here, but it allows for a lot of freedom when it comes to what can be done with this content.

Not included in those files, however, are the textures, game models and audio used in Overgrowth, so it really is a base to make new things or more involved mods to the base game.

Users will still need to own the game to make proper use of these files, which is why Overgrowth is also receiving a permanent 30 percent discount. On top of this Wolfire’s previous game Receiver is still bundled in with all purchases of Overgrowth.

Aside from the GitHub files and its supporting documentation, there’s also some other links that may come in handy aside from the overview trailer at the bottom of this story.

There’s a short video here which shows how to run the game from the source code, as well as a written document covering the same topic.

It will be interesting to see what the community does with all of this going into the future as mods made for the game before now were quite involved and it was clear that many people love this title. We wouldn’t be surprised if some full game or experience is made using these assets.
