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.

2 measurements spanning 10 days. Dots are measurements; the straight line between them is drawn to join them, not to claim we know the path taken in between — snapshots are recorded only when a count changes, so gaps mean “no change observed”, never “interpolated”. The vertical axis spans 69–71 and does not start at zero.
