I am going to run this for my players soon using Hostile (by Zozer Games). It will be my first time refereeing this game system, and I find your adventure very interesting and approachable: very suitable for a first adventure for a new system.
I had fun setting up the star system (Fomalhaut) in which the adventure is to be set, the orbital platform that services its mining colonies (The Kharkiv) and refines hydrogen from the nearby gas giant into liquid hydrogen coolant, and the space station's different sections and inhabitants.
I've switched the awful events to a scientific research ship that has popped out of hyperspace rather than the space station itself, mainly because I enjoyed the space station as a working location for the PCs to spend some pre-horror R&R in.
I'm going to go with the genetic experiment option: I love the way the adventure offers suggestions throughout for how to tailor the adventure towards the 6 different antagonists. The tables of additional enemies and set-dressing optional objects are very useful too. Great work.
