Each cannon is placed on the map wherever you see fit. When you first begin the game you have a choice of three different weapons, that each cost a different amount of defence dollars. If you deploy a weapon that is to expensive, it might not cover enough ground. If you don't deploy the pricier weapons in time, you might not have enough fire power to defeat the enemy.

Each soldier has a red power meter above his head showing how much damage from your weapons he has taken. The heart in the upper right portion of the screen is your health. Each enemy soldier that passes through your defenses unscathed will reduce your overall health.
