Robotz DX is an unashamedly old-school, single-screen shoot-em-up with strategic game play. Although simple in concept, it is a difficult game to beat; you will die many times before you master all 30 arenas - and even when you do conquer the game, it's randomly generated level layouts will provide a new challenge on every subsequent play-through.
On each level, the goal is to destroy all the robots within a time limit of 60 seconds. To destroy the (shielded) robots, the player has to blow up the red, pulsating shield emitters first. You'll know when you have successfully hit a target because it will flash white.
You'll find lots of bonuses to collect, and computer banks to use as temporary cover, or to simply blow up for extra points (and note that there is a small chance of the computers hiding an additional bonus within).
