Think of the mode in Kane's Wrath where you controlled different cities and areas. Now, think of that in generals 2, but with a greater focus on WMD's and less focus on conventional forces. Each team starts with certain territory held, and you must capture different areas to secure different types of resources and things like missile silos or bio labs for things like diseases. Different WMD's would function differently, for example, nukes would be easier to control, but in a much smaller area than something like a disease, which would be more powerful, but harder to control. To win the game, you would have to destroy all of the enemies territories or capture their home country.
