[quote=@ClocktowerEchos] Again, spooky voices and a mysterious trail of stellar empires and civilizations suddenly going poof do not look good on a diplomatic resume. People don't trust voices they can't put a face to or know the source of and are often regarded as going insane or something similar. Even if you backstab a space faring nation, the very fact that you are their last known major contact before they suddenly disappear will make people suspicious and connect the dots. This is also assuming they're completely isolated and can't contact someone else for help when their allies suddenly turn on them. In addition, space is HUGE, unless you can destroy every ship in space before they can leave the system, there are going to be survivors. [/quote] Yes, Yes, Yes. The Infestation does not care about their diplomatic stance. They have no use for allies and, if they cannot be trusted anymore, some infested will allow themselves to get captured. Later on in prison/lab/ship, they break out and infest it too, continuing its spread. They could not care less for their temporary allies and may abandon them in the middle of battle and make believable excuses to prolong their "alliance". In addition, they may Infest important people in a nation and pretend like everything is fine while the infested person changes things in law/military/information in negative ways. Basically political sabotage. Also, they want people to escape because infected people could be on the ships and can spread the plague even farther.
