A classic! The objective of Dig Dug is to eliminate underground-dwelling monsters by inflating them with an air pump until they explode, or by dropping rocks on them. There are two kinds of enemies in the game: “Pookas” (a race of round red monsters, said to be modeled after tomatoes, that wear yellow goggles) and “Fygars” (a race of green dragons that can breathe fire while their wings flash).
The player’s character is the eponymous Dig Dug, dressed in white and blue and able to dig tunnels through destructible environments. Dig Dug will be killed if he is caught by either a Pooka or a Fygar, burned by a Fygar’s fire, or crushed by a rock.
