Brian AlbertNote: At the time of posting this article, we missed that the deal also extends to the Xbox 360 and Xbox One versions of the game. The article has been updated with the missing information. Purchasing Call of Duty: Advanced Warfare on a PS3 or Xbox 360 gets you a free copy of the PS4 or Xbox One versions, respectively -- with a few caveats. To receive a free copy of Advanced Warfare on a new-gen system, you must first buy the digital base game on a last-gen system. On the Sony side, where the promotion falls under "Cross-Buy" territory, buying a PS4 version from the start nets you the PS3 copy as well. It's unclear whether buying a copy of the Xbox One version gets you a 360 copy, so we've reached out to Activision for comment. The offer expires March 31, 2015, and customers who have already pre-ordered the game can still take advantage of the promotion. All DLC, plus any progress made in the game (for example, weapon unlocks) will transfer from console to console for free. And unlike the upgrade deal, there's no deadline for when you have to do this.
