 In New Zealand , the game was banned on December 11 , 2003 , with possession deemed an offence . Bill Hastings , the Chief Censor , stated " it 's a game where the only thing you do is kill everybody you see [ ... ] You have to at least acquiesce in these murders and possibly tolerate , or even move towards enjoying them , which is injurious to the public good . " The game was similarly " refused classification " in Australia on September 28 , 2004 by the Classification Review Board , despite having already been on sale for almost a year at the time with the classification of MA15 + ( restricted to ages 15 and over ) .
