Dig Dug for Atari 2600
You've got to defend your yard from a variety of pests in DIG DUG.
Mini-dragons and creatures that look like red balls with feet and
glasses infest your garden, and you must destroy them with your pump
gun. When one of the pests get close, you can fire the pump gun and fill
it up with air. As you pump air into your enemy, he rapidly expands
until he finally explodes. If you don't have time to pump an enemy, you
can dig a tunnel under a rock and have it fall onto one of your
adversaries waiting below. After all of the enemies have been
eliminated, you move to a new stage where more and faster enemies await.
See how many mini-dragons you can eliminate in DIG DUG.
