I finished the book this morning and I have to say I liked it enough. I don't see Infiltrator blowing anyone away like Alex White's novels but it remains a solid Aliens story with interesting ideas. If I had to compare this work to other Alien novels I would put it around Alien: Prototype. It teases lots of interesting things but I don't know if the payoffs will work for everybody, the novel sort of suffers from its own nature as a prequel. Infiltrator feels like a blend of Aliens and John Carpenter's The Thing, I'd definitely recommend it to fans looking for new Alien content to read. It adds new Xeno types and alien creatures (referred to as small-x xenos), but if you expected a revealing look into what we will be seeing in Aliens: Fireteam you will be left wanting.
