1980's legendary Sandbox game is now ported with new features!

Cosmic Cavern was published in July 1980 by Takaya Arita, currently a professor at Nagoya University. This “Tactical Digging Game,” which existed two years prior to Dig Dug as the original sandbox game, has now been dramatically powered up!

Steam Keys only

We are only selling Steam keys for this title. You need to have the Steam client to play this game.

This project combines graphics by Hiroshi “Mr. Dotman” Ono, the artist behind such Namco classics as Dig Dug, Xevious, and Mappy, and sound by Yuzo Koshiro, composer of Streets of Rage, The Revenge of Shinobi, and Shenmue, to complete an arrange version in 1980s arcade style. 

Like fools, we rely on games offered for our favorite platforms that are published in magazines, but lately, they seem to have all become so simple, demanding too little of the player’s intelligence and creativity. Now a game has been created that makes us stand up and cry, “Let’s do this!!"

This quote is from an article announcing Cosmic Cavern.

Cosmic Cavern was published in the July 1980 issue of I/O Magazine in Japan. As the article illustrates, Space Cavern was extremely addictive because it allowed players to express their imaginations, was densely packed with pure fun, and was highly innovative. It gained incredible popularity and was ported to a wide range of 8-bit computers of that era.

In addition to the original version, this masterpiece compiles two arranged versions that modify frustrating parts of the original with modern gameplay, in addition to enhanced features and two-player co-op. That’s three games in one!

Hiroshi "Mr. Dotman" Ono drew graphics for these games:

  • Pacman 
  • Tank Battalian
  • Rally X

Mindware started out as M.N.M Software in 1987, as a company that constantly put out new and original ideas, based on slogans such as “Gameplay over graphics!” and “Qualitative change over quantitative change!” In 1995, the company name was changed to Mindware, and we are still trying to come up with new ideas to bring out qualitative change.
