A note on the switch to announce: /BCAST/message probably won't work as a switch trigger property.

You'd need to set up a spawner, then set up entry 1 as: BCAST/msg
Then on the switch, set the spawner as the first target, then for the switch command, use /dorespawn/true

The switch will only modify properties of the item that has been set in the switch's properties.

Also, you might want to add a RefractMin and RefractMax to the spawner so that someone can't just Last Object the switch and spam hundreds of broadcasts. Or I can show you how to set it up so that it triggers on players, possibly changing the announcement based on the karma/kills of the player that approaches.

Thanks for the tip Eru!
