A parents group down under are getting hot under collar over the content of Sega's new House of the Dead: Overkill, the Australian organisation arguing that the MA15+ certification awarded to the title isn't strong enough.

The game has already been described as a record breaker, the title containing the most swear words of any game - ever.

"The gaming has been mischievously misrepresenting the classification system on this issue," railed Pro Family Perspective director Angela Conway in a new statement.

"I feel very distressed that a large number of teenagers and adults would play this game and soak up this amount of sexually aggressive and aggressively violent language.

"We need to draw a deep breath and look at the research, which will show a need to scale back this level of violence. Given the increasing amount of knowledge now available of the effects of exposure to intense levels of violence on the adolescent brain, we should be reviewing the level of violence the MA15+ classification now allows."
