When you ring a Doorbell either you get shocked into a coma, tigger a booby trap, unleash a pack of genetically enhanced starving, rabid kittens with spiky collars, or a drunk guy named Earl whose wife just left him shoots you through the door.
Well there's Extreme baseball where you play with impact detonated explosives.
And extreme beach volleyball which is like the DOA video game. except you play with a volleyball that has retractable spikes that randomly pop out and the ball explodes when it hits the ground sending out deadly shrapnel and releasing ebola into the air.
