Berks

Your mission is to clear 32 single screens by destroying a set amount of Berks to move to the next one. As you move around the screen blasting Berks in your Terror Tank you must avoid Drones which cannot be destroyed but can be stunned. Firing your weapon though loses you energy shown by a gauge on the bottom of the screen and if you lose your energy, or touch a Berk or Drone then you lose one of five lives. There are five skill levels to choose from and these are Duffer, Novice, Normal, Expert or Master.
