Count Dooku: Defenders of Peace
The first thing you'll need to do is control one of the clones to grapple the hooks on the side of the ship. If you try to run anywhere else, you'll be zapped and killed instantly. After you discharge the electricity, assemble the rubble near your broken ship to create a little speeder.
Take a short jolt to the nearby field and build a cannon. If you're short on coinage, there are several blue studs nearby. Jump into the cannon and shoot the makeshift wall straight ahead.
From here, it's another battlefield level. Remember to disable the force fields first, then take out the satellite dishes, and find the base that has an easily destroyable defense. Once you take over one base, it's easy to work your way around the rest of the battlefield.
Note that shiny metallic robots and objects must be taken out with a cannon or other explosive weapon.
The end goal here is to destroy the device on the top-right of the field, which is being protected by a satellite beam.
