All the excitement of the arcade game comes home with this new version of DIG DUG. You guide the hungry gardener as he tunnels beneath the earth searching for delicious fruits and vegetables. But beware of the firebreathing Frygars and mischeivous Pookas, whose tough means the end for Dig Dug. It's a game of skill and adventure for one or two players.
In many ways, Dig Dug can be traced to the success of Pac-Man. It featured a "cute" main character in a cartoon like environment. It was definitely looking to appeal to both sexes.
