The full set of instructions explain all this better than I can here, but it's good to know they did follow through with this functionality. But even then, it might be possible to pull your save data from a USB drive or the cloud, Blizzard says. It seems relatively painless, unless of course your system is packed away, or worse yet, sold for magic beans at GameStop. The process requires your old console to be taken out of mothballs and for you to download a patch and export your save, then import it when you have the new-gen version of Ultimate Evil. In other words, you can't switch from 360 to PS3, or PS4 to One down the line. What you can't do? Hop from one generation's system to the rival brand's of the same era. Things get a bit trickier however when trying to jump from PS3 to PS4, Xbox 360 to Xbox One or even cross-brand, next-gen leaps, moving from PS3 to One, or 360 to PS4, which is indeed possible.
