Among us Event
have lobby all wear meds/mags (to hide the gun/sword of killer)
KILLERS get a pm before round saying to equip sword/ knife they are killer
mute lobby
set hp to 1-80 (either oneshot or 2 so its not super easy to mow a row of people)
host gives random tasks to lobby (maybe trivia leading to locations.)
among us ensues.
host can unmute lobby to eject people upon request and execute possible killers.
or you could allow players to vote kick suspects with the in game kick feature
issues i see at rip
the scoreboard telling who the killers are
