This was the first time Sub-Zero appeared without his mask.
First apperance of Motaro, Sindel, Stryker, Kabal, and Sheeva.
Consular instruction booklets said that Stryker didn't use his gun in battle because it "went against the tournament rules" or something along those lines. Ironically, in the next port, Ultimate Mortal Kombat III, he uses it.
The original name of Sindel during the development process of this game was Muchacha.
