Dig Dug (ディグダグ, Digu Dagu) is an arcade game developed and published by Namco in Japan in 1982. It runs on Namco Galaga hardware, and was published outside Japan by Atari, Inc..

Atari also obtained the license for home versions of Dig Dug, and released it for the Atari 2600, Atari 5200, Atari 7800, ColecoVision, Intellivision, Apple II, Atari 8-bit family, VIC-20, Commodore 64, IBM PC, and TI-99/4A. Namco ported Dig Dug to the Famicom in 1985.

Gakken made a table top handheld game of Dig Dug in 1982. It was one of a series of 3 flip-top games with VFD screen and magnifying Fresnel lens.

Gameplay

The objective of Dig Dug is to eliminate underground-dwelling monsters, either 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 cute round red monsters, said to be modeled after tomatoes, that wear yellow goggles) and "Fygars" (a race of green dragons that can breathe fire when their wings flash).

The player's character is the eponymous Dig Dug, dressed in white and blue and able to dig tunnels through dirt. 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.

It takes four (three in some versions) 'pumps' with the player's action button to inflate a monster until it explodes. A partially inflated monster will deflate and recover after a few seconds, but half-inflating is a useful way to stun an enemy for a few moments, especially to make sure it remains in the path of a falling rock. The player can also pass through the enemy while it is deflating. In some versions, deflating is slow enough that the player can execute rapid, partial inflate actions and pop a monster much more quickly than just holding the 'pump' button down.

The monsters move horizontally on the surface and both horizontally and vertically through the tunnels in the dirt. While in the tunnels they can also turn into ghostly eyes which slows their movement but gives them the added advantage of diagonal travel through the solid dirt and rock. The last remaining enemy in each round will attempt to escape to the surface and off the top left side of the screen.

More points will be awarded for exploding an enemy further down in the dirt (the levels are color-coded). Additionally, Fygars are worth double points if exploded horizontally, since they can only breathe fire horizontally in the direction they are facing. Extra points are also awarded for dropping rocks on enemies in order to eliminate them rather than inflating them. If one enemy is killed by the rock, it is worth 1000 points. The next two add 1500 points each, and any after that add 2000. The act of mining is itself worth points—giving 10 points for each block mined—so some players will do as much of it as possible when the threat from the remaining monsters is minimal.

After the player drops two rocks, a bonus item appears at the center of the screen, awarding points if the player can collect it before it disappears. These items consist of various fruits and vegetables, as well as the flagship from the Namco game Galaxian, and appear even if either of the dropped rocks fails to crush any enemies. In the original arcade version, the most points attainable from a single bonus item is 8000 from the pineapple, which appears in round 18 and every round thereafter.

If the player should drop a rock on a foe at the same time he pumps it to death, a glitch will occur whereupon all enemies will promptly disappear, but the game will not progress and the player will be free to dig through all dirt. Attaining the next level of play will then remain impossible, but the glitch can be resolved by forcing a rock to drop.

The current round's number is represented by flowers in the top right of the screen, and each new round is noted at the beginning of each round. After every fourth round, the color of the dirt will alternate (as seen in this article's screenshot graphic). In successive rounds more monsters appear on each screen, and they move more quickly. A round is completed successfully when the last monster escapes or is dispatched.

In the coin-operated version the game will end on round 256 (round 0), since the board is essentially an unplayable kill screen. When the round starts, a Pooka will be placed directly on top of where the player starts, and will kill Dig Dug instantly. There is no way to kill it, but the Atari version corrects this problem. No tunnels are drawn, save for the one that goes from the top-center to center. Strangely, a couple Pookas and Fygars also appear, but they don't have a tunnel to be placed in, so they are just overlaid onto the dirt.

Protagonist

Although Namco has given the character of the original Dig Dug the name Dig Dug, in other games where he makes an appearance, the protagonist goes by the name Taizo Hori (in Japanese order, Hori Taizo), and is the father of Susumu Hori, the main character in the Mr. Driller series. He is also the ex-husband of Toby "Kissy" Masuyo, the heroine of Baraduke. His name is a pun on the Japanese phrase "Horitai zo" (掘りたいぞ) or "I want to dig!" (掘り = dig, たい = want, ぞ = !) – a similar pun might be rendered in English as "Will Dig" or "Wanda (Want To) Dig". His real name was revealed outside Japan in the Nintendo DS game Mr. Driller Drill Spirits, where he is also a playable character. He is additionally featured in an unlockable gallery of Mr. Driller items in Mr. Driller 2. In the Mr. Driller series, Hori is known as the "Hero of the Dig Dug Incident". In Japan, he is also the Hero of the South Island incident and is the honorary chairman of the Driller Council to whom most of the characters answer. This contrasts greatly with the PC remake Dig Dug Deeper, where the hero is simply named Dig Dug.

Reception

Dig Dug was rated the sixth most popular coin-operated video game of all time by the Killer List of Video Games website.^[3]

In 1984 Softline readers named computer versions of Dig Dug the tenth-worst Apple and fourth-worst Atari program of 1983.^[4]

Legacy

Some bootleg arcade versions of Dig Dug were made, under the name Zig Zag. One version looked exactly like the original,^[5] and the other changed both the sounds and colors, as well as adding a pickaxe power-up that made the player move faster.^[6]

A Game Boy version was released in 1992 with the choices of the original and new versions was added.^[7] In 1996, Dig-Dug was included in Microsoft's Return of Arcade. Another version was released on a Plug 'N Play System, along with Galaxian, Pac-Man, Rally-X, and Bosconian. In October 2006, a version of Dig Dug was released on Xbox Live Arcade, and became backwards compatible on Xbox One in May 2016.^[8] Namco Networks ported Dig Dug to Windows (bought online) in 2009 which also includes an "Enhanced" mode which replaces all of the original sprites with the sprites from Dig Dug: Digging Strike, Namco Networks also made a bundle (also bought online) which includes their Windows version of Dig Dug as well as their port of the original Pac-Man called Namco All-Stars: Pac-Man and Dig Dug. The arcade version has also been released on the Wii Virtual Console in Japan on October 20, 2009, along with its sequel, Dig Dug II and the original Dig Dug was released as part of the Pac-Man's Arcade Party 30th Anniversary arcade machine in 2010. The NES version for the Virtual Console was released in 2008 for the Wii, 2013 for the Nintendo 3DS and 2015 for the Wii U, but as an import for Western regions when ported to the former. The arcade version was released on Xbox One and PlayStation 4 on April 20, 2016 as part of Bandai Namco's Arcade Game Series.^[9][10]

A 1985 sequel to this game, the overhead-view oriented Dig Dug II, met with less success in the arcades. Mr. Driller (1999) was originally conceived as a sequel, with the working title Dig Dug 3, but it developed into a distinct but related series. Another sequel, Dig Dug: Digging Strike, was released in 2005 for the Nintendo DS. This combined the side-view play of the original with the overhead play of the sequel and added a narrative link to the Mr. Driller series. A 3D remake of the original, entitled Dig Dug Deeper, was released for PC in 2001 by Infogrames. The original Dig Dug was released for the Xbox 360 console via Xbox Live Arcade on October 11, 2006. The original Dig Dug is also available for play via the GameTap subscription gaming service, and was shown in one of the television commercials for the Gametap website in 2005.^[11] It was re-released for the Wii's Virtual Console in North America on June 9, 2008^[12] and in Europe on August 29, 2008, at a cost of 600 Wii Points.

The original game was re-released on Steam as part of Bandai Namco's Arcade Game Series on 19 April 2016.^[13] The re-release fills a landscape orientation monitor by wrapping the game with art from the original game cabinet. Players can adjust various sound and display parameters, such as choosing a present sound mix, adding reverb and emulating TV scan-lines.
