You are a commander and you have to send units to destroy the enemy tower and defend your own tower.
The two enemies have set up camps next to eachother. They both believe that the enemy is going to attack so it's best to be the first to attack...
And the battle begins. Send units tactically or you wont stand a chance. Increase your income by sending units, cheaper units gives better income.
Here are some key features of "Tower Defence":
· Use your units strengths and weakness
