The Ground Branch Tech Preview is an early prototype development build that will allow us to work on compatibility and performance optimizations. There is no installer, just unzip it wherever you want and run GroundBranch.exe.
Keep in mind that while this is the base for Ground Branch, it is not Ground Branch "The Game". It should, however, give you a good sense of where we're heading! We encourage you to stream it, talk about it and otherwise spread the word!
Enter a 'zero' to receive the Preview for free, however, please feel free to add extra if you like. It will help us make sure that our Early Access release is the best it can be.
* This is a standalone release that doesn't use Steam or use any DRM. Feel free to share the build as well, there are no restrictions. But only downloads from the store will be automatically notified of updates.
