About Mushroom Testing Facility
You are humanity's last hope. Test on, discover, and kill the variety of parasites avaliable. Found a rulebreaker? Say "/votekick {player}" to initiate a Votekick against them! 60% of the server must vote yes for it to proceed. This game has been discontinued and will not receive updates or maintenance going forward. HEAVILY inspired by antscientist's Parasite Testing and various Innovation Inc games.
