A mysterious video game titled Cook's Mad Recipe has been rated R18+ by the Australian Classification Board, becoming the first title to achieve the new adult rating for "high impact sexual references".

The Application was submitted by European outfit Koch Media and its publisher Deep Silver of Dead Island fame, and the new owners of Saints Row and Metro: Last Light. Most peculiar however, is that the developer is listed as Eutechnyx, a UK studio known only for racing games such as Auto Club Revolution, and the recent licensed NASCAR titles.

Cook's Mad Recipe ticks almost all of the consumer advice boxes with "high impact" themes, and sexual references, "strong impact" violence, and drug use, and "moderate impact" language and nudity, all relevant ingredients for a mad brew.

Deep Silver hasn't hinted at anything that could fit the description, but we've reached out to our local reps for comment. In the mean-time, speculate away: An adventure game chronicling Captain James Cook's secret smuggling operations? Grand Theft NASCAR? A seductive action game starring Nigella Lawson and Jamie Oliver? We can only hope.

Update: A previous classification entry for Deep Silver's Ride me to Hell: Retribution bears a striking resemblance to the details of this new development, suggesting that it is likely a codenamed submission for the Biker-centric title, previously thought to be cancelled (Thanks Crash). Cook's Mad Recipe is perhaps a reference to a methamphetamine cook in the game.
