Stronghold Crusader Extreme includes a new trail and a new map loaded with over a dozen sick-and-twisted challenges that will put any self-proclaimed experts to the test. The game's battle system has been greatly improved, including the power to summon up to 10,000 troops to your aid. There is full multiplayer support for friends to battle it out in various scenarios. Along with the new content and abilities, players will find the complete original Stronghold Crusader game to play through as well.
