Xbox teams up with Teenage Mutant Ninja Turtles for pizza-scented controllers

Xbox is to release new pizza-scented controllers - but only to gamers who win a competition.

To promote the upcoming release of Teenage Mutant Ninja Turtles: Mutant Mayhem in cinemas, Xbox said it built a world-first with the wireless gaming controllers that come with a built-in scent diffuser shaped like a slice of pizza.

Fans have reacted swiftly - and hungrily - to the news, with many unhappy the controllers are limited only to sweepstakes.

"Why are these giveaway only, they are so cool," one complained on Twitter.

Another worried about their waistline if they used them.

"Pizza-scented? Oh dear I'd get hungry every time I play my Xbox," they said.

"Because everyone wants their hands to smell like pizza," another puzzled.

However, the announcement from Xbox didn't reveal what flavour the diffuser would be pumping out while you were sweating away in front of your favourite game.

"That would be funny if someone asked for a pizza with pineapple-scented Xbox controller," asked one.

There are four variations of the controller to tie in with each of the four turtle brothers, with each representing the signature colours, weapons and personality of Turtle brothers Leonardo, Raphael, Donatello and Michelangelo.

The giveaway runs from July 24 to August 13 and details can be found on official Xbox social media platforms.
