The box stood out on the shelves of computer stores like few others yet had. An injection-molded face mask—stark white plastic inset into the surface of the oversized package—stared out at shoppers browsing aisles of less memorable software packaging. Above the mask, the word SUSPENDED in bold block capitals, broken by a blood-red EEG brainwave. Behind the mask’s eye-holes, shadowed, were wide-open eyes. Those who bought the box, took it home, and opened it up would see they were part of a sketch: a face behind glass, hooked up to electrodes, eyes and mouth wide open in a silent scream.
The game on the floppy disk behind the sketch had a similarly startling premise. In nearly every previous text adventure, the player had controlled a “player character” who could be directed to move around the world and take actions; the parser would report back what that character was seeing and experiencing. But in Suspended, the character you’re playing never moves. They never even open their eyes.
They said you would sleep for half a millennium—not an unreasonable length of time, considering you’d be in limited cryogenic suspension. Your body would rest frozen at the planet’s nerve center, an underground complex 20 miles beneath the surface. Your brain, they told you, would be wired to a network of computers; your mind would continue to operate at a minimal level, overseeing maintenance of surface-side equilibrium. And you would not awake, so they promised, until your 500 years had elapsed—barring, of course, the most dire emergency.
Then, and only then, you would be awakened to save your planet by strategically manipulating six robots, each of whom perceives the world differently. But such a catastrophe, you have been assured, could not possibly occur.
As Suspended begins, your character—the frozen human guardian for a planetary network of automated systems—has been brought to the surface of consciousness to respond to unexpected disaster. “Your body will be warmed to the point where marginal biological activity is resumed,” the game manual explains, “supplying your mind with the necessary nutrients and oxygen to function at peak capacity.” But your body remains frozen. The manual explains that you’ll interact with a crew of repair robots in the underground complex via a series of Filtering Computers (FCs), which will interpret your commands and translate the robots’ reports back to you. The Filtering Computers are a diegetic explanation for the game’s parser. The textual interface, and the disconnect between player and character, are part of the story.
Each of the six robots is specialized to understand a specific kind of data about the world. Only Iris can see. Sensa detects vibrations, Waldo can grasp objects and perform delicate actions, Auda can hear, Whiz knows things, and Poet has his own unique way of perceiving the world—“a psychedelic James Joyce,” as one reviewer called him. Through the robots, you must diagnose and repair the damage to the planetary control systems from an ongoing series of earthquakes—before the dying people on the surface decide to replace you.

Suspended was released by Infocom, the company founded by the creators of Zork, including Dave Lebling and Marc Blank. “This business began as a lark,” Lebling once remarked, “and it is looking less larky every day.” By 1983 Infocom was becoming one of the most successful and respected game companies in the US market. A sales chart for a week at the end of that year showed an astonishing ten Infocom titles in the top thirty bestselling games: no other publisher came even close to that level of dominance. Today there’s a popular narrative that Infocom’s text games only sold well because graphics weren’t yet around, but the truth is more complex: “Back in 1981,” Blank recalled, “we were told by distributors that we were crazy. Nobody wanted text games any more.” Yet Infocom made it to the top of the charts with only their text regardless, which might go some way toward suggesting how compelling it was.
The company had been founded in June 1979, but its first commercial product, a microcomputer version of Zork, wouldn’t ship until December 1980. Even trimmed down for home computers, Zork became a massive hit: it was the bestselling game through the first half of the 1980s. A pair of sequels were quickly produced, and in 1982 the company released Marc Blank’s Deadline, a murder mystery with more of the plot and characters familiar from traditional media. The company’s move toward more sophisticated stories began to turn heads. A 1983 Time Magazine article was one of dozens that year scrambling to herald the arrival of a new kind of literature, or at least of mass-market entertainment:
[Deadline] is part of the latest craze in home computing: programmed fiction. Machines that were used mainly for blasting aliens and calculating monthly budgets are now also churning through adventure tales and murder-mystery plots. “It’s like reading a novel, only you are the protagonist,” says Science-Fiction Writer Linda Bushyager. While arcade-style games like Pac Man are losing popularity, these complex programs are winning more and more fans. ...Judging from recent sales, the text programs are more popular.
But the Zork alums were growing conscious of the fact that they were mostly programmers, not writers, and perhaps not the best folks to usher in the next evolution of the novel. At the Boston Applefest computer meet-up in 1982, Blank met another creator of text games with an intriguing pedigree: he was a published science fiction novelist, and he knew how to program. Blank soon hired him to begin work on a new game that would keep Infocom innovating.
The man was Mike Berlyn, quick-witted and curly-haired (also “high-strung” and “chain-smoking,” according to one reporter); a three-time novelist—graduate of the prestigious Clarion Workshop for sci-fi and fantasy authors, in the 1975 class—and two-time text adventure author. He and his wife Muffy, also a writer as well as a journalist and artist, had started a company called Sentient Software and become some of the first professional writers making text games with their 1981 adventure Oo-Topos. They quickly followed it up with a second game, Cyborg, which like Mike’s novels was fascinated by questions of human-machine interfaces and perspectives:
I CAN'T LOCATE THE EXACT CAUSE OF OUR MALFUNCTION. OUR POWER UNITS HAVE BEEN SO BADLY DRAINED BOTH OUR LONG-TERM AND SHORT-TERM MEMORIES HAVE BEEN DAMAGED. ...THE ONLY DATA AVAILABLE TO EITHER OUR ORGANIC OR SILICON MEMORIES RESIDE ON A SINGLE CHIP: YOU AND I ARE PERMANENTLY LINKED. WE ARE SEPARATE ENTITIES SHARING AN ORGANIC AND METAL SHELL...
The Berlyns brought a refreshing notion to their early titles: the idea that games built from words might aspire to be more like traditional stories. “CYBORG is a unique approach to gaming,” the back of its box declared, “with no treasures and no score. It contains character development... and a consistency found in no other adventure.” It was exactly the perspective Infocom’s founders had hoped to find. While Muffy wasn’t officially allowed to collaborate on Mike’s new game—Infocom had a policy against hiring spouses of employees—Mike has said she “contributed extensively” to Suspended and “helped design” all his text adventure games. The two would go back to collaborating officially as soon as Mike left Infocom in 1985, and would make many more games together in the following decades.
But back in 1982 as Mike moved into his new office at Infocom, he was faced with a daunting possibility space. “In one sense we are working within traditional genres,” he reflected, “and in another we are still teaching ourselves, laying out the groundwork for what these things could be. For the most part, we are working without pioneers.” Mike was a writer/programmer when there was no model yet for what such a role should be. Infocom’s founders had hoped the programming language they’d devised to author their games—ZIL, the Zork Implementation Language—might be comprehensible to a tech-savvy writer. Descended from MDL, the MIT research language itself descended from LISP, it came with a lot of flexibility and power. But the conceptual model of a LISP-like language was vastly different from the BASIC Mike had worked with before. “I was kind of sat down in front of a terminal,” he recalled, “and [they] said, ‘Okay, here you go. Have at it.’ I was brought in I think as their big experiment. Here’s a writer, [who] kind of knows what he’s doing. You know, let’s give him a shot.”

ZIL’s ability to nest complex behaviors and functions in lists—which could contain anything from strings to more code—gave it a useful flexibility that made it possible to implement the many complex routines of an unusual game like Suspended. By contrast, the tools designed for the Adventure International games or MUD were simpler to use, but could only create the specific kinds of adventures those tools were designed to enable. ZIL had fewer assumptions about what a text adventure was “supposed” to be, making a radical departure like Suspended possible—if not exactly easy to code.
Both coding and playing the game required a different kind of thinking than anything that had come before. The player’s location, senses, and agency become fractured between six limited entities, causing what one fan dubbed “a thousand little mysteries” in piecing together a coherent picture of the environment from limited clues. Take identifying an object: one robot might grasp it in its manipulators and describe it as “a rough device,” while another sees only its electromagnetic emissions and calls it “a scanning device.” Whiz can determine it’s “a CX1 chip,” Iris can see that it’s blue, and the whimsical Poet calls it “brain uno.” Only by synthesizing all this information in the context of its environment can you come to understand it’s a scanning processor chip, useful to repair a malfunctioning robot.
Understanding your role in the game, and learning how to direct your robot avatars, requires careful study of the game’s manual and the bonus materials inside its imposing box (making it all but inscrutable to modern players who might not have access to this content or even know it exists). The instructions, for instance, detail commands that wouldn’t appear in any other Infocom game, ways to give multiple robots orders or get them to work together:
>sensa, follow waldo FC: Cryolink established to Sensa. SENSA: Okay. I'll follow Waldo. >waldo, go south FC: Cryolink established to Waldo. WALDO: Internal map reference -- Gamma Repair I have reached the south end of this area. The walkway ends here. The walkway is not in motion. In the room with me is Sensa. There is a hollow object here. The hollow object contains... A broken mechanism >waldo and sensa, examine broken mechanism FC: Cryolink established to Waldo. WALDO: I perceive nothing special about the broken mechanism. FC: Cryolink established to Sensa. SENSA: I perceive nothing special about the broken device. >waldo, get broken mechanism FC: Cryolink already established to Waldo. WALDO: I can't manage it. The broken mechanism is too heavy. >both waldo and sensa, get broken mechanism FC: Dual-Cryolink established to Waldo and Sensa. FC: The robots have moved it. FC: Cryolink established to Waldo.
But in addition to gaining mastery over your environment, you must also figure out how to do it quickly. “The first time you play Suspended will not be your last,” say the game’s instructions: this is less because of particularly gripping storytelling than because it takes many playthroughs to gather enough information to solve it before time runs out. A succession of disasters, culminating in your disconnection by angry surface-dwellers, leads to game-over after 160 turns, a fraction of the time one would spend to solve a game like Zork. Like someone caught in a time loop, each playthrough is an opportunity to learn a little more about the crisis you’re caught up in and how to repair it; each game you can spend a bit less time experimenting and a bit more carrying out your plans. Suspended, one reviewer noted, is “a marathon that requires conditioning.”
But even after you’ve figured out how to solve the game—and how to do it in less than 160 turns—you still haven’t won:
FC INTERRUPT: All systems returning to normal. Weather systems slowly approaching balance. Hydroponic systems working at full capacity. Surface life in recovery mode. Extrapolation based on current weather systems and food supplies: Total recovery in 82 cycles. Current surface casualties: 4,277,000 Projected casualties during recovery: 3,417,000 Original population: 30,172,000 Total possible survivors: 22,478,000 This score gives you the possibility of being considered for being burned in effigy. On a scale of 1 (the best) to 7 (the worst), your ranking was 7.
Every couple turns, your score goes up by a few points: but this is not a good thing. Each point represents a thousand casualties on the surface of the planet, as the damaged planetary weather, traffic, and hydroponics control systems go haywire. To truly beat the game, you must optimize your repair plan even further, trying to complete your tasks in the fewest turns possible and keep as many citizens alive as you can. The manual offers some tips:
Moving your robots one room per cycle can be extremely costly. You may find it easier and more efficient to direct a robot (or more than one) to GO TO a room so you can do something else while the movement is taking place. Robots will progress one room per cycle and will tell you when their destination is reached.
But this is just the beginning of the complex ballet an optimized run of Suspended becomes, with no command wasted, each motion choreographed: a precision akin to that seen in modern speedrunning. Skilled players use the six robots like a single machine to relay objects to precisely where they need to be on the turn they need to be there. Since you can enter only one command on each timestep, sequencing and shuffling orders to avoid robots waiting for an item or event becomes crucial. Like an assembly programmer optimizing each cycle of code, the goal is to streamline each task down to the minimum number of steps, and find the most efficient way to order and thread them together. Many reviewers have noted that while Suspended starts off as interactive fiction, its endgame is some other genre entirely, closer to the complex cooperative board games like Pandemic or creative optimization games like Opus Magnum that would appear decades later.
Reactions to the game at the time were largely positive, but also buoyed by an electric sense that Infocom was in the process of radically evolving what a computer game could be. “Suspended represents another milestone in the continuing evolution of the interactive computer novel,” Softline Magazine wrote: “This form of literature may be one of the most important waves of the electronic age, and Michael Berlyn and Infocom will certainly be riding on the crest of that literary wave.” The game sold a hundred thousand copies in a time when very few computer games could; only a handful of Infocom titles would ever sell more. No less impressive a tastemaker than Rolling Stone reviewed it and called it the best computer game ever made. It attracted the attention of prominent writers like Douglas Adams, who would go on to co-author multiple games with Infocom. And at the 1984 CES trade show in Las Vegas, counterculture guru Timothy Leary stopped by Infocom’s booth and was blown away. “He certainly understood the fractured reality concept of Suspended,” Berlyn would later recall. “I couldn’t rip him away from the machine, and all he had to say was, ‘And this is legal?’” Leary would later write that the game forever changed his opinion of computers; he’d go on to help create the surreal 1986 game Mind Mirror. “It was, oddly enough, Timothy Leary who said that I had changed his life,” Berlyn recalled with a smile years later, “which was kind of funny.”
The game’s longer-term legacy would be more complex. Its alienating premise and interface turned off players expecting the more traditional storytelling that was becoming the core of Infocom’s brand. It was also challenging, uncompromising, and required an obsessive attention to detail: “a game for frustrated would-be air traffic controllers,” one reviewer called it. The first Infocom game created by a writer, it had less plot and characterization than nearly any of their other titles. Today many consider it one of the company’s lesser works, more notable for its unusual packaging and bizarre premise than its often tedious gameplay.
Yet Suspended helped change the perception of what a game could be, expanding horizons that until then had seemed more limited. As Leary realized, it didn’t use text simply as a poor substitute for graphics, like most other adventures: a caption for a photo instead of the real thing. It used its words instead to create a different kind of reality in the mind of the player, in a way that only text could achieve. A graphical version would miss the point of imagining what it might be like to experience the world solely through touch, or electricity, or poetry. While the particulars of its approach were rarely repeated—and graphics would, of course, soon come to dominate games after all—Suspended planted a very visible flag that said the status quo didn’t always have to satisfy. There had been weirder games, but they hadn’t topped the charts; there had been experiments in form, but not from Infocom. Story games could aspire to be more than awkward adventure novels, and bestsellers could be cerebral.
In a somewhat glib and giddy 1984 interview, the growing group of Infocom creatives were asked what they thought about the future of computer games:
Meretzky: There’ll be a lot more variety, there’ll be kinds of games that you can’t even imagine.
Berlyn: I can’t imagine that. But we are working on the future.
Blank: Yes, we’re building one in our backyard.
Next week: When Infocom collaborates with another novelist, one of the most beloved of the day, the result would be a game legendary both for its meta-level humor and its hair-scratching puzzles.
Activision, the rights holder to the Infocom games, has done only a sporadic job at keeping them available to modern players: as of this writing there is once again no legal way to buy it (so hey, here it is; you’ll need a standalone z-code player like Lectrote to run this). Players will definitely want to first read the background materials that came in the box and the manual before tackling it. A vintage hint booklet or modern walkthrough might also be helpful. You can also view the ZIL source code. Most major sources are linked inline; thanks again to The Digital Antiquarian for coverage of Sentient Software and Mike Berlyn’s pre-Infocom career.
This is easily my favorite newsletter of the year. I'm 28, Choose Your Own Adventure is the only one of these I ever played! Now you've got me doing a deep-dive on Infocom at the digital antiquarian lol.
This is one of the few Infocom games I've never replayed. It was so much work at the time (I bought it for the Atari 800 back when the original face mask package was still being sold) to solve it. I took copious notes, now lost, and kept replaying it to optimize the game. I'm not sure if I hit the optimal solution or not, but I spend dozens of hours on it in the early 80s. But it's not a game that one remembers well decades later, because the story, plot, the room descriptions and images, are all kind of secondary points to the main part of figuring out the timing and events and what can mitigate them. I remember enough of Infidel, Deadline, the Zorks and the Enchanter/etc triology that I can replay them nearly 40 years later without hints. To reply Suspended would require recreating all my work, or using a walkthrough, which kills the point.
Here's a "decompiled" to "pseudo-Inform" version that's a bit easier to read than the ZIL: http://plover.net/~agarvin/suspended.inf.txt (I did most of the work on this before we had the ZIL sources so I had to figure out variable function slowly by context, and give them names of my own choosing).
