Developed by Namco and released by Atari, Dig Dug is a "strategic digging game" that has players digging their own mazes underground while eliminating Pookas and fire-breathing Fygars with a pump and falling rocks. The enemies initially appear in dug-out sections of the screen and normally follow in the paths you have dug, but they can also move directly toward you through the dirt. Dig Dug has a fair amount of strategic depth despite its relative open-ended gameplay, and its cute characters and charming soundtrack made it an arcade mainstay in the early 80s and have made it popular ever since. The overlay includes a larger screen version so you can really get your face in the dirt.
