Baseball pitchers in the house?
Of course, they're too powerful if you place self-propelled launchers in a confined space.
Sometimes there are four of them in one room, so you hardly have a chance to enter the room.
My suggestion is to only use them outdoors, with a certain radius that you can also see when you place them, but to have a weaker alternative in the house that you can buy later, since several windows, etc., have already been destroyed.
