Desperate to get your hands on Dishonored, and can't wait until October 12? Well, you're in luck. Bethesda has released a somewhat sickening Fruit Ninja clone called Dishonored Rat Assassin for iOS.

In the free game you must help rid Dunwall's streets of rats, the source of the deadly sickness infecting the city's citizens.

Use a number of supernatural abilities - such as Bend Time, Shadow and Adrenaline Kills - that will be featured in Dishonored to complete your task of slicing and shooting each and every rat across 12 challenges.

You can download Dishonored Rat Assassin for free over on iTunes.
