If you would like to rename roles in game you can do so with specific ConVars. This effect works server side ONLY and will automatically network the role names with any clients playing on your server.
To rename a role set the ConVar ttt_ROLENAME_name
to whatever you would like that role to be called. (e.g. ttt_quack_name "Death Doctor"
will rename the Quack to the Death Doctor.)
NOTE: The game will try its best to automatically generate articles and plurals for any new names, but it is not always successful. If this is the case you can use ttt_ROLENAME_name_article
and ttt_ROLENAME_name_plural
to manually fix this.
ttt_oldman_name_plural
to "Old Women" will fix this.ttt_innocent_name_article
to "an" will fix this and properly show "an Honest Man".
