Sega managed to overturn a ruling by the Australian Classification Review Board, who at first refused to give Aliens vs. Predator an age rating in Australia effectively banning the game. It has now been given a 15+ rating, which means that only people above the age of 15 are allowed to buy the game. I guess this means Sega can't put any "Banned in Australia" stickers on the box in order to make it sell more elsewhere...
There will not be any revisions or cut made to the game, something that developers Rebellion were not to keen on at any rate.
