Buy a digital copy of Dead Rising 3 from the Xbox One Games Store between January 27 and February 9 and you'll receive a free HD copy of World War Z to own on Xbox Video.
The offer forms a part of Xbox Live's Zombie Week, which apparently kicks off on the service today, and marks an £8.99 saving over buying the movie separately.
To receive the free film you'll need to live in the UK, France, Ireland and Austria and be over 18 years old. Eligible customers will receive a code to download the film within 7 days of purchasing Dead Rising 3.
