Scorpion

Scorpion is a clone of Centipede for the VIC-20, but there are a few tweaks. The centipede in Atari's popular game has been replaced by a group of scorpions that make their way down a field of cacti towards the player who must go left or right, shooting at the scorpions to destroy them. Spiders appear and fly across the screen to make your job even harder, and spores drop down, leaving a line of cacti in its path. Shoot both of these for bonus points. Get rid of the scorpions to proceed to the next level. Contact with any one of the creatures will result in a loss of life, and losing all your lives ends the game.
