This is an optional rule for violent video games.
You go to the Options Menu. Inside the Options Menu there's an on/off slider next to the words DANCE ABANDON. If you move this slider into the On position you will have activated HEADLESS DANCING WITH ABANDON MODE, which basically entails the following: everytime you decapitate an enemy, instead of just falling over, the enemy's headless corpse starts dancing with wild abandon. The Charleston. The Fox Trot. The Cabbage Patch. The Can-Can. The Lambada. The Watusi. The Running Man. The Viennese Waltz.The Roger Rabbit. Adult Contemporary Ballet. The Boot Scootin' Boogie. It's a little bit of everything.
And as they dance, these headless corpses create a kind of bloody rain machine effect what with all the spurting neck stumps and such. Totally slicks down the streets. Really gives a glow-up to all the lighting effects. Everything looks like Blade Runner or King of New York or the battle in the rain from Seven Samurai, but with lots more blood.
Now, this is all strictly optional. Sure.
But I bet the more you think about it, the more you'll probably feel that DANCE ABANDON should just be default if not mandatory.
Truly, it is neat.
