The ants want a piece of your delicious cake and take it back to their anthill. It is up to you to stop them getting away with your cake and ruin your perfect picnic. Unlike other tower defence games the invading ants in Ant Buster don't follow a fixed path but instead choose their own path to navigate through your cannon defence. The cannons have a limited range so place your cannons next to the ants to destroy as many as possible. The cannons will automatically aim and shoot the nearest ant but you can also click and target and individual ant. When you select your tower cannon and click in the buttons of the panel or the keys 1, 2 or 3 you can see the possible upgrade improvements also. You can also undo any upgrades or sell your tower.
