I wonder how it was implemented there. I don't know if I ever saw dual game ports on the PC. But then, by the time I was looking at PCs, I think it was a feature of sound cards.

@foone @SDoleMelipone The C64 version shipped with the Lip Stick, though. This was sold as a sophisticated voice activated system that increased the game's immersion.

It was effectively a Clapper attached to the Joystick 2 fire button.

So, yeah, maybe you're right about the better port...

I recall sending Access a few dollars to get the filled out map, but they'd already gone out of business by then.
