Solar forces are still holding out on the besieged island base at Tiki Bay, but the Xylvanians have moved to crush them with a pair of goliath Battlestations! You are their only hope of resisting these giant war machines!
Purge the beach of Xylvanian infantry, order all units into Sentry Mode, and switch control to a Gunship once the Ack-Acks are dead. Destroy the MG Towers nearby so that your Bazooka Vets can fully assault the first Battlestation. Once the goliath machine is gone, switch control to an Assault Vet and set the Gunship into Sentry Mode. Call the other infantry, and set off down the road, using the Assault Vets and Rifle Grunts to take out the enemy infantry, and Bazooka Vets to blow up the MG Nest. The second Battlestation would have started its charge to the Imperial-held base by now, so run across the first bridge and take out the enemy infantry and MG Nest to claim your reinforcements. Take control of an Anti-Air Vehicle and blow any nearby Fighters out of the sky. Order all units into Follow Mode, and roll across the bridge leading to the Solar base. Shoot down any other nearby Fighters, then take control of a Gunship again. Fly over the Solar base for added defence, and order all units to attack the second Battlestation. The mission ends when the second war machine is destroyed.
