"MK Is Coming"

Acclaim's campaign for the home release of Mortal Kombat used a dedicated hotline, coordinated television advertising, and the controversy over the SNES censorship versus the Genesis blood code to generate record single-day sales.

Acclaim designated September 13, 1993 "Mortal Monday" — a simultaneous release date for both the SNES and Genesis home versions — and built a campaign around scarcity, hype, and controversy. A dedicated hotline (1-800-4SEGA for the Genesis version) allowed players to call in for cheat codes, and Acclaim purchased television advertising across every major US market in the weeks preceding release. The campaign benefited enormously from a controversy it had partly manufactured: the SNES version shipped with blood replaced by sweat and fatalities altered, while the Genesis version retained gore through an unlock code. Gaming media reported extensively on this difference, effectively providing free advertising. Congressional hearings on video game violence — which began shortly after Mortal Kombat's arcade release — kept the game in mainstream news through the entire home release campaign.

Impact: Mortal Monday generated an estimated $50 million in retail sales on its first day and the controversy directly precipitated the creation of the Entertainment Software Rating Board (ESRB) in 1994.
