For players (role messages and commands)
Only you see your role
Only the host who creates the room needs the mod. Everyone else joins with the normal (unmodified) Among Us on PC, Switch, mobile or console. When the game starts, your role and what it does reach only you, on your name tag and in chat. The opening screen only says Crewmate or Impostor, so check your real role on your name tag and in chat.
A few seconds after joining, the enabled roles and rules are sent to you in chat (visible only to you).
Chat commands
/cmd h… help (command list)/cmd n… your role/cmd r role… role description/cmd lang en… language of the messages sent to you (ja / zh / en)/cmd about… about this mod
In a role room, /cmd lines go only to the host. Nobody else sees them. Players limited to quick chat (consoles and so on) can’t type commands, but still get their role messages.
