Can we get some parasite aliens? They could control of players and make it so they cant talk. Then eventually burst out and start killing people when there is a group near. Thought this would be a really neat addition. No idea how they would make it to/into the ship though.

We already have the husks which are actual parasites, I think it's better if we make it so that if you get stung by a husk; it infects you with a small bacterial-sized husk that if left untreated will kill you (pop your head and have a parasite replace it) and turn you into another Husk (without the suit on). This, coupled with allowing Husks to transmit parasite-strains onto a dead body will revive that body as another Husk.
