Mortal Kombat and the Video Game Violence Panic That Created Game Ratings

For a few months in 1993, the most urgent question in American living rooms wasn’t about a movie, a TV show, or a piece of legislation — it was about whether a video game called Mortal Kombat was turning children violent. The game itself was a two-player fighting game, mechanically not wildly different from Street Fighter II, which had already been a massive arcade hit. What made Mortal Kombat different, and what eventually got it a hearing in front of the United States Senate, was the “Fatality”: a finishing move performed on a defeated opponent, rendered in digitized blood and genuinely grim detail — spines torn out, heads removed, bodies set on fire.

A Secret Code Everyone Knew

The violence wasn’t even fully visible by default. The arcade version’s blood and Fatalities were switched on by a specific code — hold a button combination at the character select screen — which, naturally, every single kid playing the game knew within days of it appearing. The “secret” code spread by word of mouth across playgrounds and arcades so quickly it might as well not have been secret at all, which only added to the game’s mystique. Parents walking past an arcade cabinet and seeing a spine being ripped out had no idea it required a deliberate input; as far as they were concerned, this was just what the game did.

Two Versions, One Scandal

When Mortal Kombat came to home consoles in 1993, the console wars accidentally created a natural experiment. The Sega Genesis version shipped with the blood code intact — players could still unlock the full gore. The Super Nintendo version, due to Nintendo’s much stricter content policies at the time, replaced the blood with grey “sweat” and toned down the Fatalities considerably. The result was a sales gap that told its own story: the bloodier Genesis version significantly outsold the sanitized SNES version, a fact that did not go unnoticed by either the games industry or the lawmakers who were about to get involved.

The Senate Gets Involved

In December 1993, Senators Joe Lieberman and Herb Kohl held congressional hearings specifically on video game violence, with Mortal Kombat (alongside the FMV shooter Night Trap) as the central exhibit. Industry executives were called to testify, game footage was played for the committee, and the hearings generated exactly the kind of national news coverage that made “that violent video game” a dinner-table topic even in households that had never seen it played. The threat on the table was real: a government-mandated ratings system, imposed from outside the industry, if the industry didn’t create its own first.

The Industry Rates Itself

Facing that threat, the video game industry moved fast. The Entertainment Software Rating Board (ESRB) was established in 1994, introducing the now-familiar letter ratings — EC, E, T, M, AO — that still appear on every game box and storefront listing today. It was, in effect, a direct and fairly immediate consequence of the Mortal Kombat panic: a self-regulatory system built specifically to get Congress to back off, which it largely did. Every “M for Mature” label a modern gamer glances at and ignores traces its existence back to a Senate hearing room and a finishing move involving a spine.

What Actually Happened to the Game

Mortal Kombat, for its part, was neither killed nor chastened by any of this. Sequels kept the gore, kept selling, and the series remains one of the most recognizable fighting game franchises in gaming history decades later — now rated M as a matter of course, with nobody needing to find a secret code to see exactly what they’re getting. The panic that once put it in front of the Senate reads, in hindsight, as the origin story of an entire labeling system the industry now takes for granted, born from a moment when a cartridge full of pixelated violence briefly became a genuine national controversy.
