As announced back in June, Beenox and Mercenary Technology will be porting Black Ops 3 to the previous generation consoles. Activision has now revealed more details on what had to be removed to get the game working on the Xbox 360 and PS3.

Black Ops 3 is a next-generation experience, as stated multiple times by Treyarch, and has been designed from day one to harness the power of the Xbox One, PlayStation 4 and PC. Unfortunately the Xbox 360 and PS3 just can't cut the mustard and will only feature multiplayer and zombies. The singleplayer campaign requires more processing power than the previous generation hardware can handle.

"The Black Ops 3 PS3 and Xbox 360 versions will feature Multiplayer and Zombies gameplay only, not Campaign. The ambitious scope of the 1-4 player coop Campaign design of the PS4, Xbox One and PC versions could not be faithfully recreated on old generation hardware."

Some other features, like the eSports tools and Weapon Paint Shop, will also only be available on the Xbox One, PS4 and PC. Due to these missing features the Xbox 360 and PlayStation 3 versions will be sold at a discounted price and Activision is also giving each copy a bonus download for the original Black Ops game.
