I must have gotten the game a long time ago off humble bundle and I want to know if I am gonna purchase the game again off the site and get the loyalist tier, is their a way for me to upgrade to it or can I at least pay the full loyalist price but get a copy that I can give away but keep the extras for me? Is there an option to just upgrade instead? I want to get the highest tier available since the release version of the game blew me away and I wanna support the devs more and try to convert some friends too.
If you’re talking about the KS rewards, you can’t obtain them. If you want to support the developers, be active in the forums, on the Steam Discussions, and just keep playing the game.
If you bought from Humble I believe there is a way to upgrade, if you bought from Steam, there is not.
In either case, if you buy a full price version, you have one Steam key to give away.
EDIT: here is the thread about upgrading
