Back on another post by the way, the infestation does have limitations. 1: the virus is no-longer airborne. The virus must be in special living conditions in the air to stay alive. 2: the only way to infest something now is to contaminate something with the virus by touch. To be clear, the virus can survive for a while after contamination because the infested flesh produces a fluid that is filled with the virus and has the living conditions required to live on the contaminated object. If something touches the contamination, the virus slips through the skin and infects the inside. If the contamination stays too long without a host, the virus collects itself and creates the infested flesh on the object, e.g: counter, floor, wall. 3: as legion02 discovered, the Hive Ship weapons are weak and most are almost useless in space.
