"After careful consideration Warner Bros. Interactive Entertainment Australia have decided to appeal to the Australian Classification Review Board against the RC (Refused Classification) decision given to Mortal Kombat. After reviewing both the game play and the Board's original decision WBIE Australia believe the violence in the game is on par with numerous other titles readily available for sale in the Australian market. As such the company wants to exhaust all options to make the game available to Mortal Kombat fans in this country. An identical version of the game will be submitted for appeal."For more information on the R18+ classification for games in Australia, see this website
