I thought the Bishop one was decent, just some missed opportunities and a terrible ending.
This book is very poorly edited. I've caught a "Ridley" in place of Ripley, an author using the word "corp" in place of corps (as in Marine Corps), smaller typos, and one author confusingly referring to Weyland-Yutani as W-T. Also, "double-X" instead of double-Y chromosomes when referring to the Fury 161 prisoners.
I've also read in an Amazon review that author's notes are left in one of the stories? If someone has caught that I'd be interested in page numbers.
Made it through several more:
Deep Background
Spoiler
Pretty good account of an embedded journalist, I thought it had a good ending. This is more of the type of story I was hoping for.
Empty Nest
Spoiler
I remember this one being decent, but kind of forgettable. The inclusion of Xenomorphs and other creatures so often throughout this kind of cheapens the idea that the Colonial Marines were unprepared in Aliens.
Darkness Falls
Spoiler
This took me three sittings because I kept falling asleep. Features Xenomorphs birthed from centipedes. Silly.
Hugs to Die For
Spoiler
This one was decent because of the characters. Mostly focused in an attack by a giant pile of facehuggers.
Deep Black
Spoiler
This one is probably my favorite in the book so far, about a special ops team that returns to Fiorina 161 and discovers a ship has landed and the crew has been killed by aliens. This is the one where the author refers to WY as W-T for some reason, and referenced "double-X" chromosomes. Other than that, I thought the story was well done and really interesting, a good concept that hasn't been explored. Unfortunately it ended right as it could have potentially got interesting. So, in many ways, another missed opportunity. Seemed like a good start to a novel though.
EDIT:
Finished it, and of the last three, Dangerous Prey is really good and the other two are forgettable. Overall I'm disappointed.
