The PlayStation 3 and Xbox 360 version of Call of Duty: Black Ops III are being developed by Beenox and Mercenary Technology, while the PlayStation 4, Xbox One, PC (Microsoft Windows) version of the game are being developed by Treyarch. Due to the fact that the seventh/last generation consoles have less powerful hardware, there are a few changes to the last generation version. These changes are:
The campaign/story mode is not available
The multiplayer beta was not available
Custom paintjobs aren't available
Ground War won't be available
