The two big ones I participated in were early alphas for two Ubisoft games: Ghost Recon Breakpoint and Riders Republic. Both were in pretty early states and neither had release dates. Heck, I don't think Riders Republic had been announced externally at the time. They were early enough in the development pipeline that voice acting wasn't even finalized, with lots of dialogue relying on placeholder text-to-speech. I had to sign NDAs to play both and a slew of personal information was splattered across the screen at any given time so screenshots could be traced back to me if I leaked any.
Felt kind of cool to see the work in progress.
