W/S = Move Robot Space = Robot Attacks Before each battle, click to select the turrets and explosives (within your budget) you'd like to bring onto the battlefield. Then click START THE WAR. In battle, click a turret and then the place you'd like to build it. (Tip: Start with a Generator Turret to make sure you have enough power to build other turrets.) Click the blue energy balls falling from the sky or generated by your Generator Turret. Click the icons in the top-middle of the screen to demolish or repair turrets. Kill all enemies before they kill you.
