First it was only in movies, then came the idiot boxes and then perhaps the worst--3D interactive shooter video-games: all of them geared to 'satisfy' their blood-thirsty audiences. Well, with arrival of video-games, 'audiences' became 'players', which is perhaps the reason why their popularity reached its zenith in a relatively short span of time. Psychologists have been warning about the psychological menace video games can cause quite for a while, particularly among teens and hence Australian Office of Film and Literature Classification (OFLC) seems to be just going in right direction when it banned the ultra-violent Dark Sector.

Dark sector is a production of AFA Interactive. Truly a 'masterpiece' of it's kind, this video game includes ultra-violent moves and motions like dismemberment of limbs followed by blood spruts, neck breaking spurts, neck breaking twists and exploded bodies with post-action twitching body parts, everything followed by equally realistic sound-effects. Above has been stated as the official reason by OFLC while refusing to rate Dark Sector.
Australia is known to have no official 'adult' ratings for it's entertainment industry and hence the rules seem to be more rigid for its offenders. Meanwhile, Adam Zweck, sales and product manager for local distributor of AFA Interactive has vowed to explore many legal loopholes so that the game hits Australian shelves.
