I've got my hands on the Starter Kit and I'm making my way through it now.
It's got a history, from Weyland's TED talk to post Fiorina 161 (there's a cult surrounding survivor Morse and his book 'Space Beast' he wrote about whathappened, which is really cool), and it not only covers the alien but also the governments, corporations and factions.
It's giving the players a chance to play the horror of Alien, the action of Aliens or the mystery of Prometheus. If you wanted to do something that doesn't involve the alien and stick to some corporate craziness - like Outland - then that's cool, too. There are plenty of options for all kinds of games.
I'll be starting the rules soon, but up to yet I'm loving what I'm seeing. They're based on the system they uses for Tales from the Loop and Coriolis and it works well, but it's not the full rules as they're leaving some of it for the full rulebook. However, I ran a Coriolis campaign last year and the system handles dark sci-fi really well, so I think this'll be a good fit.
Additional: Also, the GM is called the 'Game Mother'. Brilliant!
