Dig Dug
Dig Dug is a classical platform-game from Namco
The player controls Dig Dug, the hero of the garden. He moves through horizontal and vertical tunnels. When Dig Dug digs new tunnels he moves slowly. When he is on the surface or in an existing tunnel, he moves faster. The object of the game is for Dig Dug to destroy all the monsters and go to the next round.
Game play takes place on a cutaway section of the land. The characters are Dig Dug and 2 monsters - one is a round, orange monster with goggles called Pooka, the other is a green, fire-breathing dragon named Fygar. The underground area is divided into 4 different colored layers of dirt. Rocks are scattered in the dirt. The sky is at the top of the screen.
