If you're wondering what a Tenpenny Skeet Shoot is, well...In Fallout 3, get about 30-40 bottlecap mines, or triggerable explosives, set them up in Tenpenny's entry-way on the balcony, have a scoped weapon on hotkey ( I use gauss rifle, best scope IMHO) then walk behind Allistar and punch him in the back of the head. He becomes hostile and makes a run for it. Right into the mines...30-40 mines will send his corpse to the edge of rendering (scope range) Try to shoot his dead body and blow off body parts before he hits ground. This does NOT work with Bloody Mess. Enjoy!!
