CATALOG DESCRIPTION (June 1982, Consumer Electronics Show)

The excitement of defending your planet! Falling meteors, missiles, and enemy spacecraft all might knock out your position, but you have both automatic and semi-automatic firing sequences to defend against the onslaught. A one-player game with two levels of difficulty.

BUG (original production run): If two joysticks are plugged in and both moved at the same time during the game, unexpected things can happen: the laser base will fly up into space or below the bottom border, the screen will turn red, the base count will cycle from 99 down to zero, and/or the joysticks will stop operating.

RUNNING CHANGE: Later production runs of Astroblast were reprogrammed to fix the above bug.
