Call of Duty: Advanced Warfare players who digitally purchase the title on the Xbox 360 or PlayStation 3 will be entitled to a free upgrade to the title on a next-gen console.
The deal, which is available until March 31st, 2015, also applies to any downloadable content purchased for the title, including the Season Pass.
However, the upgrade only works for the same console family (so those who own the Xbox 360 version can only get an Xbox One copy).
Full details of how the deal works can be found on the Call of Duty website.
Call of Duty: Advanced Warfare launches on the PlayStation 3, Xbox 360, PlayStation 4 and Xbox One on Tuesday, November 4th, 2014.
