Players have the option of skipping over the scene. At the beginning of the game, there are two checkpoints where the player is advised that some people may find an upcoming segment disturbing. These checkpoints cant be disabled. - Says the Activision spokesman.
Modern Warfare 2 is a fantasy action game designed for intense, realistic game play that mirrors real life conflicts, much like epic, action movies. It is appropriately rated 18 for violent scenes, which means it is intended for those who are 18 and older.
Call of Duty: World at War was BBFC rated for 15 years and older (M) due to extreme violence and gore, Modern Warfare 2 has been given the BBFC rating for 18 years and older (M). Apparently setting people on fire with a flame thrower is suitable for 15 year olds but Modern Warfare 2 has things even worse. We can't wait to find out for ourselves, when time is there. Again, we ask of you to not spoiler anything off the Singleplayer campaign on the Internet!
