Start with a bi-plane which is mounted with a puny caliber gun and a handful of bombs. As you battle your way in the air through different types of landscapes and environments, earn points to upgrade to a much powerful plane.
Drop bombs with your helicopter to wreak havoc on enemy grounds while sending out troops and vehicles to take control of enemy bases. See tutorial for hotkeys.
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.
