Wacko — About this game
Wacko makes shooting a matching pair the key to clearing its monster-filled arena. A shot briefly stuns one creature, leaving a short opportunity to shoot its twin and remove both. On later boards, hitting a different creature instead mixes their body parts into mutants, requiring another matching plan. The trackball moves Kapt’n Krooz’r independently of the joystick’s four firing directions, allowing an escape route to continue while lining up the next pair. Later transformations keep the cleared pair from being the end of every target.
