Dig Dug II is the arcade sequel to Dig Dug, released by Namco in 1985. It runs on Namco Super Pac-Man hardware but with a video system like that used in Mappy. In 2005, it was ported to the PlayStation Portable in Namco Museum Battle Collection and is included in Namco Museum DS released for the Nintendo DS on September 18, 2007 in the United States. It was also included in 2008's Namco Museum Virtual Arcade. It was also released on the Wii Virtual Console in Japan on October 20, 2009, along with the first game. Both Dig Dug games are available as part of the Namco Museum Megamix compilation for Wii, which, unlike the Virtual Console Arcade versions, was released in North America only and was never released in Japan.
