PAC INVADERS combines familiar characters from PAC-MAN and the scenario of SPACE INVADERS. You need 16K and a joystick and then lots of practice. [The program] makes good use of re-defined characters set graphics. The action is relatively fast and the response time good (remember this is a BASIC program). This game could be customized into your very own version of a very popular arcade game.
PAC Invaders was published as type-in source code for Atari BASIC in Antic, Vol 1, Number 3, August 1982.
