Any way to Get a hold of much earlier Builds than Alpha 10?

The only people who have pre Steam versions (A1 - A3 I think) are the original kickstarter backers and only if they never uninstalled it because they are no longer available. Kickstarter backers played the first alphas by downloading the builds directly from The Fun Pimps. Once the game released on Steam early access those primordial builds could no longer be downloaded directly and since they were pre-Steam they do not show up on the beta list on Steam.


Also please note that a lot of the earlier versions on the beta list do not support the game launcher feature so you can only load them from the exe file.
