Mode rules and player priorities
Two players cooperate through selected Age of Empires II campaign and Historical Battle scenarios, controlling allied forces against the scenario AI. Co-op versions are separate scenario variants; their available objectives and achievements can differ from the single-player versions. Before planning the opening, identify the mode’s special win condition, starting rules, and restrictions; these determine whether economic growth, map control, survival, or direct combat should take priority. The standard random-map plan may not fit a mode that changes starting units, technology, or the way victory is awarded.
