Your mission is to assemble the robot soldiers and send them to fight the enemy robots. At the beginning of the game you can only assemble the most basic robot solider, but as you progress in the game and earn money you can upgrade to new robot types. Use the MOUSE to click the parts on the assembly line to assemble them into a robot on the lower-right corner. Once you complete a robot, it will enter the battle field. You can drag robots in the top half of the screen to arrange the fighting formation.
