Robot Arena 2
In Robot Arena 2 game you get to control one robot, heavily armed and programmed to defense the base and block the attacks of intruder units. Robot has autonomous firing system, but you will have to use radio commands to controls its movements and manage the level of its equipment. Your finall mission is to unlock all weapons, use upgrades from the most advanced level of technology and of course destroy all other enemy-robots. In-game tutorial is pretty good,so I'll skip here the explanation about controls. After you click that play button, you will be literally swarm with robots. Let the shooting spree begin!
