The in-house beta testing sessions (for the original release of Divinity 2, as well as BD) were open to those who could physically get to Larian Studios. Nothing has been mentioned about public betas for DC or D:OS.
Welcome to the forum.
Thanks for the welcome Raze!
While I'm saddened to hear that the beta tests in the past were on-site only, I definitely understand the reasoning. Here's hoping that you'll do a public testing (if only a small selected group)!
Big shout outs to all of you other Divinity players! Anyone else hoping they'll do a public test?
