Atlantis Under Attack

When Atlantis was released for the Atari 2600 in 1982, the home video game market had grown at an explosive rate. In addition to Atari itself, independent developers had established themselves in the meantime, eager to prove that they could get at least as much out of the aging hardware as the console manufacturer could. One of the most ambitious of these developers was Imagic, founded by former employees of Atari and Mattel. Atlantis, designed and programmed by Dennis Koble, was one of the games that helped the young company solidify its reputation. Koble was not only a programmer but also held a management position at Imagic. Looking back, he recalled that Atlantis had sold more than two million cartridges and was the company’s second-biggest success after Demon Attack.

The situation could hardly have been more dramatic. The legendary underwater city of Atlantis is under attack by the alien Gorgon fleet. Palaces, power generators, and other parts of the city are visible at the bottom of the screen, while enemy ships fly overhead, attempting to destroy the metropolis piece by piece with their death rays. What sounds like a minor science fiction episode on paper becomes a constant siege in the game. There’s no escape, no world map, and no lengthy explanations. Atlantis reduces the battle to a single screen—and that’s precisely where its tension lies. The city is constantly before the player’s eyes. Every successful enemy attack has visible consequences, until eventually, hardly anything remains of the once-magnificent metropolis. Even the original manual presented the attack in a highly dramatic way, making the city’s defense the focal point of the story.

Three Cannons, One Target

In terms of gameplay, Atlantis is a stationary shooter, but its controls differ significantly from the typical “left, right, fire” principle of many early Atari games. The player controls three defensive positions. On the left and right are two guard posts whose projectiles rise diagonally into the sky. In the center stands the Acropolis Command Post, which fires straight upward. Which gun is active depends on the joystick’s position: left for the left outpost, right for the right one, and neutral for the central cannon. This turns a single fire button into a surprisingly tactical system.

The enemy Gorgon ships fly over the city at various altitudes. Large ships are comparatively easy to hit but yield fewer points. The fast Bandit Bombers are particularly interesting. They’re harder to hit but significantly more valuable; a hit also destroys all remaining Gorgon ships currently in the sky. The choice of gun also affects the score: a large ship is worth 100 points when hit by the central gun, but 200 points when hit by a side turret. For the Bandit Bomber, the reward increases accordingly from 1,000 to 2,000 points. After each wave of attacks, the player receives an additional 500 points for every remaining part of Atlantis. For every 10,000 points scored, a destroyed district can be rebuilt at the end of a wave. Thus, the game combines quick reflexes with a simple form of resource management: Not every loss is final, as long as the player collects enough points.

Several game variants alter the pace or disable the central cannon entirely. Particularly noteworthy is the two-player mode, in which two people jointly operate the two outer cannons. This makes Atlantis feel less like a solitary high-score hunt and, at times, almost like the joint defense of a town.

Tricks Behind the Pixels

Technically, Atlantis was developed on a console whose limitations were already well known as early as 1982. The Atari 2600 has only 128 bytes of RAM, and its graphics architecture isn’t designed to comfortably display entire screens full of independently moving objects. Developers had to precisely control the TV image during the ongoing frame rendering process and skillfully reuse existing graphic objects time and again. It was precisely these limitations that turned many of the best 2600 games into small programming masterpieces. Koble later described the games of that era as highly technology-driven: At Imagic, he said, they had explicitly wanted to demonstrate their technical prowess—not least to their colleagues at Activision, whom the developers held in high regard.

Atlantis stands out above all for its colorful city skyline, which was unusually detailed for the hardware of the time. While many early 2600 games left large portions of the screen empty or black, Imagic presents a clearly recognizable underwater metropolis with various buildings, defensive structures, and constantly passing enemies. The city is not merely decoration. Its individual components also serve as the game’s visible status indicator. If a structure is destroyed, it actually disappears from the cityscape. Technology, graphics, and game mechanics are thus directly intertwined.

Even though a single person often wrote the actual program code for an Atari 2600 game, Koble viewed the work at Imagic as a collaborative effort. Graphic artist Michael Becker was involved in the visual design of Atlantis, while colleagues regularly contributed suggestions for improvements, testing results, and technical ideas. Retrospective accounts of the development also mention a technique introduced by Bob Smith that helped display more moving objects than the hardware would have allowed at first glance. This combination of programming tricks and deliberate graphic design explains much of the impact that Atlantis had at the time.

Curiosities About Atlantis

Part of the history of Atlantis includes one of the most curious high-score campaigns of the early console era. Imagic organized the “Defend Atlantis” competition, in which particularly skilled players could submit their scores. The problem: Experienced players could apparently keep the standard Atlantis alive long enough that a significantly more difficult version was needed for the competition. The result was Atlantis II. The enemies in this version move faster, and the scoring system was altered. The cartridge reached only a small number of qualified players and consequently became one of the most famous rare Atari 2600 games.

The competition eventually made its way all the way to Bermuda. More than 80 players are said to have reached the required qualification level; the best participants competed for the top spots and a grand prize in the form of gold. Decades later, Dennis Koble still remembered his trip to the competition and how deeply impressed he was by the participants’ skill. The best players mastered his own game far better than he could himself. This is a fine example of how quickly a specialized gaming culture was already developing in the early 1980s: developers set the rules, but players discovered methods and strategies that went far beyond what was originally expected.

Commercially, Atlantis was also hugely important for Imagic. Koble later cited sales of more than two million copies. Furthermore, the game was not limited to the Atari 2600. Versions were released for the Intellivision, VIC-20, Atari home computers, and Odyssey² (or Philips Videopac), among others. These were not always simple copies. The Intellivision version, in particular, took a much freer approach to the basic concept and added new gameplay mechanics. Atlantis was thus not only a successful cartridge but also evolved, at least for a short time, into a small Imagic brand.

Praise, Skepticism, and Awards

Contemporary reviews clearly show why Atlantis stood out in 1982. The Video Game Update gave the announced Atari version an extremely positive review in July, awarding the top rating of four stars for graphics and an equally high score for gameplay. Even more interesting is the context: Imagic was explicitly recognized there as one of the strongest new developers. The magazine placed Atlantis alongside titles such as Demon Attack and Cosmic Ark and concluded that Imagic was among the best developers in the then-rapidly growing market for Atari-compatible games.

Other publications of the time also particularly praised the graphical presentation. Electronic Games, JoyStik, and Video Review all highlighted the visuals of the Atari 2600 version positively. Opinions differed, however, regarding the game’s difficulty. JoyStik found the game to be appropriately challenging, while Suzan D. Prince in Video Review criticized Atlantis for being too easy, even in its harder mode. This precisely illustrates a typical characteristic of early high-score games: to casual players, they could seem frantic and demanding, while very experienced players eventually figured out their mechanics so thoroughly that the difficulty level could no longer keep up.

Despite such objections, Atlantis also received official recognition. At the fourth annual Arcade Awards in 1983, the Atari 2600 version, along with Activision’s Starmaster, received a “Certificate of Merit” in the “Videogame of the Year” category. Although Imagic’s Demon Attack won the actual grand prize, this award alone demonstrates the stature the company had achieved by that point. Atlantis was not just another filler title on the ever-crowded cartridge shelf, but a game against which the quality of independent Atari developers was measured.

More Than Just a Shooter

The cultural influence of Atlantis lies less in the fact that countless later games directly copied its mechanics. More important is what it represents within the early history of console gaming. Alongside Activision, Imagic belonged to that generation of independent developers who broke away from Atari and, for the first time, proactively presented their programmers as the creators of the games. Dennis Koble later recalled that both Activision and Imagic made the individual contributions of their developers visible on packaging and products—partly in response to the lack of recognition for programmers that had previously been common at Atari. Atlantis thus also represents a phase in which the name of the game developer itself slowly became a selling point.

At the same time, the game demonstrates how effectively packaging, backstory, and on-screen graphics could already work together in the early 1980s to transform an abstract point-scoring game into a small world. The motif of the destructible city reinforces this impression. Unlike in many shooters, it’s not just a “life” that disappears from a counter; Atlantis itself crumbles. The player watches as individual structures are lost and struggles to rebuild them by earning enough points. This lends failure a visible sense of drama.

Added to this is the significance of high-score culture. Campaigns like “Defend Atlantis” linked the game cartridge to advertising, magazines, submitted scores, and real-world competitions. A video game no longer necessarily ended on the TV at home. It could become an occasion for comparison, competition, and the emergence of a gaming community. The fact that Atlantis II is known today as a rare collector’s item precisely because of this competition makes the connection between the digital gaming experience and the physical object particularly clear. And finally, Imagic dared to do something else: the story of Atlantis was not meant to end completely with “Game Over.”

A Downfall with a Sequel

Atlantis is, from today’s perspective, a remarkably focused game. It takes only one screen, three cannons, and a few passing enemies to create a clear rhythm of observing, deciding, and firing. Its strength lies not in enormous complexity, but in the combination of simple rules. The side cannons require good timing, the central cannon provides security, valuable bombers tempt you into risky shots, and every lost city district increases the pressure. At the same time, the reconstruction system ensures that a battered city isn’t immediately lost. If you play well, you can pull Atlantis back from the ruins time and again.

Then there’s the presentation. The colorful skyline, the visible destruction, and even the auditory cues for particularly dangerous enemies give the game more atmosphere than one would expect given its extremely limited technical capabilities. The original manual explicitly recommends listening for the characteristic hum of the Bandit Bombers instead of constantly firing blindly. Even the sound thus becomes an integral part of the game strategy. Atlantis is therefore a good example of that phase in video game history when technical limitations weren’t simply hidden, but rather gave rise to a unique aesthetic through precise design.

But eventually, even the last line of defense falls. Atlantis is destroyed. And it is precisely at this moment that the game delivers what is perhaps its most surprising twist: A spaceship rises from the sinking city and escapes into the sky with the survivors. This ship served as the link to another Imagic game, narratively connecting the two otherwise very different titles. Rob Fulop, the developer of Cosmic Ark, also recalled the idea that the same small spaceship was meant to appear in multiple games.

So the inhabitants of Atlantis haven’t simply vanished. Their home is lost—but their journey is only just beginning.

Where they are fleeing to, what awaits them there, and why the defense of a sunken city suddenly turns into a cosmic rescue mission leads directly to the next chapter: Cosmic Ark.
