I've just finished the game, so now's a great time to try the beta. Just to be clear, though...
All full-game saves are compatible with the beta version.
All beta saves may not be compatible with beta updates...
But after the beta updates, full-game saves will still be compatible with the updated beta?
Have I got that right? If so, that'll work fine for me. I can just load any old saves from whenever to try out different areas. That sounds good.
