How do they come up with all those fatalities? It's the question that's been puzzled by interviewers for longer than we remember. We've seen concept sketches and motion capture in the past. Now Ed Boon has revealed some of his original 2010 notes for an iconic stage fatality. Take a look:

Mortal Kombat 3 first introduced the perils of The Subway stage, where players could uppercut their opponent into the path of an oncoming background train. For the 2011 Mortal Kombat reboot, the series co-creator came up with something more ambitious.

Boon uncovered the 2010 notes on his iPad and shared a nostalgic screengrab to Twitter. He apparently finds amusement in the suffering of his characters, describing the notes with a laugh as an example of the "germ of an idea" that all game features start with.

The notes roughly describe what became the new Subway stage fatality, where players will grab their opponent by the throat and walk them to the platform edge to thrust their head into the path of the train. After banging against each oncoming car, the loser is then tossed into the background to be swept away by another train.

Stage fatalities recently made another return in Mortal Kombat 11: Aftermath. You can catch a glimpse of the Shaolin Trap Dungeon and Tournament Arena finishers in the Aftermath launch trailer.
