I absolutely love the name of this thread. It makes me crack up every time I open the new plugins page. Well done OP.

EDIT: Explosive headshots don't work outside of MvM as far as I am aware of, just like the medic's shield (although the medic's shield can be overriden with a plugin). Still the point is that explosive headshots may not work in pvp. You can try testing it by seeing if a group of bots players are nearby, type sv_cheats 1, nb_stop 1, headshot one, and see if it explosively kills another.
