Hm... dont they do that already?
Or maybe I'm not understanding correctly because when you say state I think of the position of the ents and such.
Just equipment. I'm talking
everything. The on/off state of trigger (hurt, for example, if you want to kill everyone who's still alive). The position of funcs (water, for example, if you want to kill everyone who's still alive via rising water). And other stuff. While we're at it, why not add a func_endround?
