VIC Avenger for the Commodore VIC-20
is a version of Space Invaders
for the Commodore VIC-20. The gameplay remains the same as in Space Invaders
; the goal
is to defend the Earth from attacking aliens. The aliens are arranged in 5 rows and start at the top
of the screen; they march horizontally and when the edge of the screen is reached drop down a level and reverse
direction. Players control a laser cannon which moves along the bottom of the screen and need to shoot all
of the aliens before they reach the ground. The aliens aren't completely defenseless and are
constantly dropping bombs which the player needs to dodge. To help out, there are four shields just above
the laser cannon which the player can hide behind. The shields aren't immune to fire, and each time
the player or an alien hits one a small part is eliminated. From time to time a flying saucer appears and
crosses the screen along the top; the saucer doesn't attack, but can be shot to earn bonus points.
The game ends when either an aliens lands on the ground or all of the player's laser cannons are destroyed.
Points are earned in the game for shooting aliens and the flying saucer.
