Your mission in this war game with a futuristic twist is to keep your base safe by shooting down all waves of incoming space bugs. Use YOUR MOUSE to control the game. Move your cursor to the edges of the screen to look around the battlefield (alternatively you can use WASD or ARROW KEYS). Click LEFT MOUSE BUTTON to pick a tower and use it to shoot incoming enemy units. You can also build your own units for increased protection. Use the mouse for all these. Good luck!
