That's according to series creator Hideo Kojima, who has admitted that one next-gen version of Ground Zeroes looks better than the other.
In an article in GameInformer, as reported by VideoGamer, it states that "Kojima notes that MGS V looks slightly better on the PS4 compared to the Xbox One, something we also noted before he mentioned it".
It is not yet known if there are any specific differences between the resolution and framerates of the two SKUs.
Kotaku has also been thumbing the GameInformer piece and notes that a playthrough of Ground Zeroes’ campaign can be completed in under two hours.
Of course, as an open-world title with plenty of side missions there’s of course plenty more available to players than that.
Metal Gear Solid 5: Ground Zeroes launches on PS4, Xbox One, PS3 and Xbox 360 on March 20 in Australia and New Zealand. Metal Gear Solid 5: The Phantom Pain, for which Ground Zeroes is a bite-sized taster, is out at some point in the future.
