Buildings also have guard zones, which trigger the deployment of local militia. Finally, terrain, fortification level, and morale are also factored into combat. Though this may sound complex, companies, regiments, zones and more are all explained in simple terms in the tutorials. The whole system works very well and becomes second nature after your first campaign scenario. The computer AI is relentless and provides a challenge even on normal difficulty level.
Skirmish mode is also available, as well as a full-featured map editor.
As expected, playing with human opponents adds a whole new dimension to the game. Kohan supports up to 8 players with LAN, Internet connection and through GameSpy Arcade's free player matching service. Multi-player games are highly customizable and the politics lore allows you to make offers for peace, declare war, and ally with other players. There seems to be a decent sized community of gamers on GameSpy, and you can find several different clans posting on the Homepage message boards. The games I played were great fun and I experienced no slow-downs or bugs.
