It's not every Missile Command clone that has tiny stick figures plummeting from the buildings when they crumble. It's a special one indeed that adds a tiny ambulance driving onscreen to carry away the remains. Touches like these, along with superior graphics and variety in level design, make this a Cadillac of shoot-em-ups.
Important: This game is not compatible with the Macintosh Plus (or anything newer). To emulate it, you will need the Mac 128K or 512K variation of Mini vMac (and a matching ROM.)
