Buy Turrets, and defeat the Martians as they try to invade Earth! You can't place turrets on the track or on other turrets. Once you have finished placing Turrets, click the start button to start a wave. You can also click on placed turrets to see their range and press anywhere else on the map to hide it. You can trash turrets as well. Infinite Waves!!!
