User blog comment:Callofduty4/Black Ops II will be Non-Linear and a Sandbox game/@comment-95.16.90.3-20120502202619

The multiplayer is in the future, half the campaing is also in the future controlling David Mason (Alex's son) and half the campaing is in the 80's controlling Alex Mason. AND the campaing will be open, you will have to make choices that will affect the ending, and there will be a lot of Sandbox sections in wich you will be in a big open battlefield, and you can use vehicles, drones, different ammos, give﻿ commands to your squad... to complete your objectives.

All this info is CONFIRMED! Yay!

And the horses are part of Alex's campaing, not the future, wich makes sense now.
