Mortal Kombat II expanded upon the success of the original with multiple new characters, a continuation of the first game's plotlines, a refined fighting system and more. In addition to improving the graphics, making the gameplay more aggressive and attacks more varied and powerful, the sequel introduced a wider range of finishing moves — new Fatalities, including two per character, as well as stage-based Fatalities and humorous Babality and Friendship finishing moves (a relatively rare instance of a high-profile game parodying its own gameplay). Mortal Kombat II was an even greater success than the original, in arcades as well as on consoles, though its notoriety led it to be banned in Germany and helped usher in game rating systems.
