Fortunately, I got my work cut out for me with Alien as it turns out, because a rules document for this game was made around 2020 or so. I figured I’d provide a link to it here because it was hidden on Pinside and felt it would benefit from being more widespread. The document provides some background info on the world of the Alien franchise before diving into the game’s rules. Props to everyone involved with the original document.
Rumor has it, the rules doc was never able to be finished because none of the games stayed operational long enough to complete it.
also the remakes and the older ones have differnt code they do plan to put out an update for the older ones to get them more in sync.
