"In The Peninsular Campaign, two players can play online or over a network, either working co-operatively to eliminate the French or working against each other to win supremacy in the region."

These are the words written by Mark in the Penisular Campaign blog and I wonder if you can actually play Coop with a friend this time around or if you still must auto resolve battles against AI as we had to in the previous campaign mode . If they made real coop possible (like if you could divide your troops in battle with your friend) I would definately buy the DLC.
