This was an enjoyable book, I really liked the threat posed by the Necromorph and some of the action was well written, there is some downsides though, at least for me personally.
I find the disease works way too fast than any disease should, mutated or otherwise, certain characters with potential are let down or end up making stupid decisions.

Tamar could have been a great complex character as it does seem she was going to be up until she pulls a burke and manages to get herself killed as well as someone else, all out of greed. Aleta is not giving much to do which is a shame as I was curious to see what such a apathetic corporate character would add to the story as she reminded me of Darcy from Musical spheres and Andrea Rollins. Another stupid thing is that despite testing potential fatal diseases on test subjects, Gagnon kept infected test subjects in a room with a large air vent... Also lesions or no lesions, the Necromorph should not have been able to withstand concentrated fire like that but ultimately I am happy with the way it is eventually dealt with, both tense during and satisfying afterwards.
Overall it is a great book and it should work as a good counter to isolation novel where the Aliens are killed fairly easily.
