I was playing the SP Co-Op Campaign with 3 friends tonight, for many, many hours. We ran into a few issues.
On the 4th mission, Red somethin another, it bugged out after we loaded a save and was unable to be completed, until we started all over.
On the mission after where it goes all freeform, everything was great until one of us was shot. We loaded the save, and everyone was not connected right to eachother. I was driving our Humvee, two passengers saw me driving it sort of right, but the gunner saw us as standing still.
This happened again. And again. And again. The only way to get around it was to not load saves, and to completely restart the missions if one of us died or anything went wrong.
So I ask this : Are we supposed to be able to load saves in Multiplayer? Because from my experience tonight, it's absolutely not working as intended, in fact, it's breaking the game for us. Everytime someone gets killed from 300m away by an AI shooting through bushes that we can't see, it sets us back 30 minutes to an hour of doing the SAME stuff over and over again.
Even if it could be set up so that we could respawn back at the base camp on the longer freeform missions, or anything like that it would be fine. But having to load a save is making this game unplayable.
