Command: Modern Air/Naval Operations - players have operational control over units on a 2D map of the Earth. Similar to Harpoon, players can command their units using preset missions or by giving direct instructions like "Come here, do this." The size and scale of battles depend only on the scenario; the engine can handle small patrol boat operations all the way up to global war, with hardware performance being the only significant limitation to scaling. Individual scenarios range from several hours to several days in real time, although time can be accelerated to speed up operations. Currently, multiplayer is not included in the commercial license for any game in the series.
