I was actually thinking something like that nuke myself.
The MCTN (Map Clearing Tacticl Nuke(hence the Modern Warfare refrence))
It would act like a clear all bricks function, but would also kill every player with a huge bang.
It would be half client sided and half server sided. The client side would be the big boom, and the server side would be a pressure wave, all bricks being killed, and all players.
In short, you would only experience the emitters and the sound if you had this mod.
