The third level of the Evil campaign requires you to capture the Shire. This mission is pretty easy, up to a point. When you reach the part where you must build a base in the Eastfarthing, built it with two of each building (including Fortresses). Also, build at least ten Sentry Towers and upgrade your Fortress to the maximum, then build all your Fortress expansions as Mountain Giants. Stay in your base and repel all Dunedain attacks until you have killed them all. You will be notified when all Dunedain are dead. When you reach the part where you must destroy the three remaining Seats of Power, only send one Goblin horde to destroy them, as there is pretty much no resistance with the Dunedain defeated. Do not destroy the Seat of Power in the bottom-left corner of the mini-map. At this point, build a large army with at least 750 command points available. Purchase all available upgrades for your Goblins, then send all your units to the large, grassy field at the bottom-left corner of the mini-map, just south of the last remaining Seat of Power. Destroy the last remaining Seat of Power with as little units as possible, then retreat a short distance to the north. This is necessary because a volley of arrows will kill many goblins if you remain in that grassy field. After a couple seconds, quickly return to the grassy field and a large army from Isengard will emerge, led by Grima Wormtoungue. Fight this army until only two Goblin hordes remain in your forces. Send these troops to your base and build as many Goblin hordes as fast as you can. In a very short time the army will attack your base. Do not try to defend any other buildings besides one Goblin cave and your Fortress. Uruk-Hai will lay waste to your forces in a short time, but your fully upgraded fortress should hold them back while you create more Goblin hordes. After awhile of relentless Uruk-Hai attacks, the flow of enemies will stop. At this time, rebuild your base and construct a large army, then lead this army into the Isengard base and kill Grima. This part of the level is very difficult, as the Ballista will quickly destroy your units. Destroying the Ballista first is recommended, if not necessary.
