Use the tower's new and unbelievably cool Super Activated Abilities to lay waste to the endless swarms of balloons. You'll need all the firepower you can get to combat the new Balloon types and new tracks with moving parts and tunnels.
Ancient machines evolved and captured the people of the planet. Get rid of old machines. Destroy them using a catapult and improved bomb. You can gain extra points if you get the artifacts. Good luck!
