There was a book released called River of Pain, it takes place at Hadley's Hope, the setting for Aliens before the outbreak. I listened to the audiobook on Audible(it's a full cast dramatisation) and it was really good. It would make a really good game.
Yeah it's excellent, it's part of an official canon extended trilogy. It's really interesting seeing how the colony got over run.
It could easily be adapted in the same style as Isolation from the POV of the main book protagonist.
