The Berks have arrived, they are everywhere, protected by their ever faithful homig Drones, which cannot be destroyed (only stunned temporarily). Your mission – clean each territory (29 screens) of the mindless Berks using your expanding Terror Tank. The number of Berks left to be destroyed is indicated in the bottom of the screen. How long can you survive?

Scoring: 50 Points per Berk, 10 Points per stunned Drone.
If you reach level 29, the game will ends.
