ディグダグ
"Dig Dug" was met with a long series of sequels for several platforms. The first of these, "Dig Dug II", was released for Japan in 1985 and was less successful, opting for an overhead perspective; instead of digging through earth, Dig Dug drills along fault lines to sink pieces of an island into the ocean. A second sequel, "Dig Dug Arrangement", was released for arcades in 1996 as part of the "Namco Classic Collection Vol. 2" arcade collection, adding new enemies, music, power-ups, boss fights and two-player co-operative play.
