This is decent, but could be improved in a number of ways. It's got good bones, but the combat overshadows the human element.
My biggest complaint is that this is basically D&D in space (but actually still in a dungeon) using Mothership rules. There's only really one way this is intended to end, and it's pretty combat-heavy throughout. It's a decent little dungeon-crawl scenario, it just doesn't really fit the Mothership vibe in my opinion.
The layout and art are serviceable, and the plot is fine, but there isn't really anything to solve, and there aren't really many meaningful player choices that resonate. Sure, there are mechanical tradeoffs to be decided on, but there are no real stakes aside from picking your flavor of danger.
