Isengard is a two-player map in The Battle for Middle-earth II and its expansion pack, consisting of the circular fortress of the wizard Saruman and the fields south of it. The player within the walls of Isengard has better defenses, more command points, and if they're an evil faction, then they can chop down the many trees for resources. However, the wolfs outside allows the player outside to level up their troops fast. They also have more room with which to build more structures.
