Stronghold Crusader Extreme is basically a buffed up version of the original Stronghold Crusader. The most significant feature is that a player can now have up to 10,000 units on the playing field at a time. It also includes 30 new stand alone maps that can be played in multiplayer or single player skirmish. It also includes a brand new Crusader trail- the Crusader Extreme trail - A heavy duty, 20 mission trail that will test the nerves of even the most hardened ‘Stronghold Crusader’ expert! This new trail also includes the 8 new A.I. opponents: The Wazir, The Marshal, The Emir, The Abbot and The Nizar.
