Defend yourself and eliminate all your enemies to survive by placing towers at available spots in Antarctica. Use strategy and upgrade wisely. Best of Luck!
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.
Prepare for the battle to protect your base and complete your Lone Ops by taking down enemy troops. Upgrade your artillery and special attacks as needed.
