The boxing ring has an administrative room a user may noclip into. This room includes buttons, two to toggle a glass cage around the ring, as well as a button to say one of five "time to fight" announcer voices.
Spawns and shop entrances can be toggled in the room described above. More importantly, this can be used to prevent users going on the other team for a team-locked event, but this can also be used for events taking place in an arena.
The spycrab room has a control room that can be noclipped into as well. This room has close, open and taunt message buttons. Rather than using glass, this room has a player clip and a bullet clip to prevent outside players hitting the buttons, and so you can see who is taunting from the room.
Many other fun rooms exist because why not.
