The Genesis Mortal Kombat Blood Code Is Because of Genesis

Abacab.

In 1993, when the video game Mortal Kombat was ported to the Sega Genesis, the development team made a secret code in the game that spelled out “Abacabb” (with two “B”s) on the controller pad. When activated, it would enable uncensored blood (Game Informer #230 Dan Ryckert p.98). This was a deliberate reference to Genesis, one of Ed Boon’s favourite bands, which happened to share the same name as the console to which the code was exclusive.
