All right! all right! This is some great news! Definitely looking forward to it
I got into Mutant: Year Zero far later than most folks I expect ... coming into it because of the ALIEN RPG around 2019.
I grabbed M:YZ just to see if there was other stuff I could steal from it to add to ALIEN (um, YEAH!) but ... M;YZ hooked me on its own merits.
Fantastically well structured as both independent standalone pieces and as an over-arching story arc.
The part that really stood out to me were the Ark rules - making it about progress, not just survival like so many post-apoc games do.
And the story arc feeds into and from that ... and ... until now, has felt "incomplete" because Mutant: Ad Astra was that missing piece.
Great news ... now... how do I wait a few more months? Must distract myself... maybe an M:YZ solo game?
