Two classic arcade games, Space Invaders and Pacman, combined into one.

Your spaceship sits in a Pacman-like matrix surrounded by dots(mines) and pursued by Martians.

Instead of devouring the mines you have a highly effective laser which allows you to destroy whole rows of them for initially impressive scores.

I say initially impressive because as you progress through the levels (1-9), the machine code speed of the program makes the higher stages extremely difficult, with frantic Martians chasing you for all they are worth.

I have shown Power Blaster to several people, whose reactions have confirmed my opinion that this is one of the best non-cartridge games I have yet seen for the unexpanded Vic.

Highly addictive, although very simple in concept and easy to play. Either keyboard or joystick can be used.

If I had to make a criticism of this game then it would have to be that, at £9.99, it is quite expensive. No more so, though, than many other Vic-20 games, which tend to cost more than programs for rival machines.
