Xenogears ends by telling you it was the fifth of six. Two words over black after sixty hours — EPISODE V — and then the credits, with nothing anywhere in the game that explains them. Every player who has finished it has heard the claim since: five other games were planned. The claim is true, it is documented, and the document says considerably more than the people repeating it usually pass on.
That document is Xenogears Perfect Works ~The Real Thing~, the official setting collection published months after the game shipped. Its preface is titled “The Truth of Episode V.” Two pages lay out all six episodes — an era for each, a distance in years, a summary of what happens in it — and then, at the sixth, the book stops and tells you it isn’t going to say. That refusal is the strangest thing in the entire framework, and it isn’t the only surprise in those two pages.
Everything below assumes you’ve finished the game. The ending is discussed directly, and so is the backstory the game withholds until its final hours.
The Card That Ends the Game
The card is not decoration. Xenogears’ full on-screen title is Xenogears Episode V, and the setting book treats that as the game’s real name rather than a flourish at the end. The preface opens by putting a number on the whole thing: the story spans fifteen thousand years, and those fifteen thousand years divide into six large episodes. The game is one of them.
The book is also precise about what it thinks the game did. It says five of the six were summarised toward the conclusion of Episode V — which is the book’s own description of the long narrated stretch near the end, the one that has been treated as a compromise for twenty-five years. Perfect Works doesn’t treat it as a compromise. It treats it as the place where the rest of the saga got delivered.
The framework is grouped, too, and this is the part that gets dropped in translation. The six episodes are not a flat run from one to six — they sit in three parts, and those parts are wildly uneven. Episode I stands alone as the first. Part two swallows Episodes II, III, IV and V together, ten thousand years of history inside a single bracket. Then the third holds Episode VI, alone again.
Read that way the number changes meaning. Episode V is the fifth episode by count, but it is the closing chapter of the middle part — the last movement of the second act, not a slice lifted from the middle of a queue. The game ends where a part ends. That is why it lands like an ending despite how much it leaves open.
The book’s proportions say something as well: Perfect Works gives two pages to the entire six-episode saga, and seventy-eight to the Gears — full-colour plates, specifications, cutaway art. The scaffolding for five unmade games takes up less room than the machine documentation for the one that got made.
What the Book Says About the Four Before
Four eras, four premises. None of them is a plot in the sense a game would need — the book gives each episode a setting, a cast and a turning point, then stops. What survives reads closer to a pitch document than a script.
| Episode | Era | When | What It Covers |
|---|---|---|---|
| I | Period of the Interstellar War | 15,000 years before | Humanity leaves Earth, settles Neo Jerusalem, and builds Deus as the war escalates |
| II | The Origins of a New Era | 10,000 years before | Cain founds a new humanity and is worshipped; Abel refuses the belief |
| III | The Zeboim Civilization | 4,000 years before | A sterile high-technology society; Kim’s nanotechnology; Emeralda is made |
| IV | The Solaris Campaign | 500 years before | Cain founds Solaris, the surface revolts, and the Day of Collapse ends the war early |
| V | Xenogears | The present, year 9999 | The game |
| VI | Future | Shortly after Episode V | Undisclosed |
Episode I opens on Earth, fifteen thousand years before the game, with humanity looking for somewhere else to live. It finds a planet in the M24 star cluster and names it Neo Jerusalem. Then it keeps going. Five thousand years later humanity holds most of the Milky Way, and the Interstellar War begins. Episode I covers the outbreak and the escalation — and, quietly, the development of Deus. The weapon that tears the Eldridge apart in the opening movie is built during a war the player never sees a minute of.
Episode II is the one the opening actually touches. Ten thousand years before the present, Cain founds a new generation of humanity and is worshipped as a god by it. Abel, the only survivor of the crash, refuses the worship and looks for another way to live. Cain spends the episode working toward the revival of Deus.
The Episode II entry states it flatly: Cain never intended to liberate humanity the way he does in Episode V. The player meets Cain once, at the end, choosing to break the cycle he built — and that change of mind took ten thousand years the game never shows a frame of. That same material numbers humanity in stages. Zeboim’s people are the third-stage generation, the war generation is the fourth, and the cast you play is the fifth. The generation number tracks the episode number.
Episode III is Zeboim, four thousand years back, and it is the closest the framework comes to science fiction about us. Zeboim reaches roughly our own level of technology and cannot reproduce — a genetic defect surfaced as the civilisation peaked, and most of its people cannot have children. Kim, whom the book identifies as Abel’s first transmigration, tries to solve it with nanotechnology and fails, because Miang has other plans for the era. Emeralda is made here. So is the nanotechnology Taura revives thousands of years later.
Episode IV is the war the game spends its entire runtime in the shadow of. Cain decides human evolution has finished and founds Solaris, then moves for the first time to rule the ground below directly rather than through proxies. The people below have learned to use Ether by then. They refuse. What follows is the great war of five hundred years ago, and it doesn’t end in victory — it’s cut short by the Day of Collapse.
Episode VI Is a Blank the Book Refuses to Fill
The sixth entry says nothing. Episode VI has no era name. Where the other five carry a title — Period of the Interstellar War, The Zeboim Civilization — the sixth carries only the word Future. It gets a place in the overview level with the rest, and it uses that place to decline: the information, the book says, “will remain undisclosed until future notice.”
Two other things are stated. It sits shortly after Episode V, and it is the last point on the timeline. Then it stops. That is the entry.
Which makes it different in kind from the other four. Episodes I through IV are documented because they already happened — the game references all of them, and the book is filling in what the game gestured at. Episode VI hadn’t happened. There was nothing to fill in. Modern reference work on the series says as much: neither the game nor the book explains what occurs there, or when.
That is a strange thing to write in a book about a game that had already shipped and would not be getting a sequel. It isn’t a refusal. It’s a promise structure — it presumes a later disclosure, by someone, at some point.
As long as I’m alive, I’d like to give an answer someday. — Tetsuya Takahashi, February 2018
He said that twenty years after the game came out, when a fellow developer asked what had become of the six-part plan. The room reacted out loud. He hasn’t repeated it or added to it since.
Why Only One of the Six Got Made
The five didn’t get cancelled. There was no meeting where a sequel was killed. Three separate conditions failed in sequence instead, and by the time the last one failed there was nobody left at the company to argue about it.
Square ran an eighteen-month ceiling on development at the time. Xenogears negotiated that out to two years, and Takahashi has described having to ask for it. Even at two years it didn’t fit. When it became clear the game would not finish, the instruction from above was to cut it off wherever it happened to be — and by his account, cutting there would have meant the story simply disappearing. The narrated second half was what the team improvised instead of losing it.
He’s been asked whether that was an artistic choice. His answer is that it wasn’t aesthetics, it was a brawl — the shape a refusal to lose took. He has also said the same decision would never get through today, and, more surprisingly, that building the game out conventionally to the end might have produced something merely additive, and that the damage may have made it better.
Then the second condition. A sequel was contingent on the game selling a million units. Domestic sales in 1998 came to 891,675.
That’s a shortfall of about a hundred and eight thousand copies — roughly eleven percent. Not a flop; a near miss against a contractual bar, on a game that has since placed first in reader polls asking which title players most want a sequel to. Around the same period, Square was concentrating development resources on the Final Fantasy film.
The third condition was the staff. Core people including Takahashi left over the sequel question and over differences about how the company was being run, and founded Monolith Soft with Namco’s backing. By then the five remaining episodes had run out of a schedule, then out of a sales figure, then out of a studio.
The narrated second half reads differently once you know what it is. It isn’t a summary of Episode V’s remaining plot — the book describes it as the point where five of the six episodes get summarised. Every era compressed into that stretch was, at one stage, going to be a game of its own. It isn’t a shortcut through the chapter you’re playing. It’s the other four at speed.
Episode I, Rebuilt Under Another Name
Xenosaga is not a prequel. It’s built on the Episode I concept — the interstellar war, the oldest point on the framework — and that much is accurate. What it isn’t is a continuation. Rights problems meant the setting had to be taken apart and rebuilt from the ground up, and the rebuild changed load-bearing pieces: Zohar, Earth and the Wave Existence all work differently across the two.
The cleanest description is the one Japanese writing reaches for — Xenosaga remade the premise rather than continuing the story. One concrete detail settles it. The Episode I era timeline in Perfect Works and the Xenosaga timeline are a few years out of alignment. Not incompatible in spirit; misaligned in the specifics, which is exactly what a rebuild looks like and what a continuation never does. Characters and machines closely resembling Xenogears’ own still turn up throughout Xenosaga. The third game is where the resemblance is most obvious.
And then the part that reframes everything above it. Xenosaga was itself planned at six episodes. It shipped three, in 2002, 2004 and 2006.
Its first game ran a two-year schedule, of which roughly eighteen months went into cinematics, leaving about six for the game. That is the same shape as the Xenogears crunch — same ratio, same outcome — at a different company, under different management, six years later. The second game swung hard the other way, scoped deliberately to what the budget and the calendar allowed, and landed badly enough that Takahashi has since said the series never earned good evaluations. Xenosaga’s own Episodes IV, V and VI were never made either.
Two six-part sagas. One shipped a single chapter. The other shipped three.
What Shipping the Fifth Chapter First Does to a Story
Starting at five is structural. Japanese writing about the game names the parallel without hedging: six episodes, and a later one released to the world first. That’s the move the original Star Wars trilogy made in 1977, and Xenogears made it on purpose.
Most of what the game gets criticised for follows from it. The opening is a catastrophe with no context because Episode I is where the context lives. Every major character is a reincarnation of someone the player never met, because the people they were are in Episodes II through IV. The exposition near the end is enormous because it was built to carry five episodes’ worth of material. Players are meant to arrive already behind. The confusion isn’t a failure of the writing — it is the writing.
The generational numbering gives the same thing away. Zeboim’s people are the third stage, the war generation is the fourth, the cast you play is the fifth. Whatever else moved around during production, the episodes were the spine.
Here’s the part almost nobody repeating the six-episode story knows. Before there were six, there were two.
The original plan was a pair of games: the war five hundred years ago, and the present day. Episode IV and Episode V. The six-episode framework is an expansion of that two-game idea — not a complete vision that got whittled down to one. Which means the familiar version of this story, where an artist’s finished blueprint was destroyed by a sales figure, has the direction wrong. The vision grew during production, kept growing after the game shipped, and the book is where it ended up, because the book was the only place left for it to go once the schedule closed.
What’s left is unusually reachable for something this mythologised. Perfect Works went out of print when its publisher folded and spent years as a collector’s item, then came back in 2014 after a reader campaign gathered close to two thousand votes; that printing sold out too, but copies circulate. The two pages carrying the entire framework are the first two pages of the book.
And the game’s second half is a different piece of writing once you know what it’s doing. Replay from the point Fei is sealed in Shevat, with the four eras in hand, and the stretch everyone calls the compromise turns into the only surviving draft of four games. Takahashi’s answer from 2018 is still standing — unrepeated, unelaborated. Episode VI is the only part of the whole framework that never had to survive a schedule.
Common Questions
Is Xenogears really Episode V?
Yes. The game's full on-screen title is Xenogears Episode V — episode 5 of a planned six — and it is the last thing the game puts on screen. The official setting book confirms it: the preface is titled "The Truth of Episode V" and it lays out a story spanning fifteen thousand years divided into six large episodes. This is not a fan reading. It is the game's own name and the publisher's own book.
What are the six Xenogears episodes?
Episode I, Period of the Interstellar War, fifteen thousand years before the game — humanity leaves Earth, settles Neo Jerusalem, and builds Deus as the Interstellar War escalates. Episode II, The Origins of a New Era, ten thousand years before — Cain founds a new humanity and is worshipped as a god; Abel refuses. Episode III, The Zeboim Civilization, four thousand years before — a high-technology society that cannot reproduce, where Kim's nanotechnology research fails and Emeralda is created. Episode IV, The Solaris Campaign, five hundred years before — Cain founds Solaris, the surface revolts, and the Day of Collapse ends the war early. Episode V is Xenogears itself, set in the year 9999. Episode VI is titled only Future, and the book declines to describe it.
What happens in Episode VI?
Nothing is known, and that is the honest answer rather than a gap in anyone's research. The setting book gives Episode VI a place in its six-episode overview and uses that place to say the information will remain undisclosed. Two things are stated: it sits shortly after Episode V, and it is the last point on the timeline. There is no era name, no date and no summary. No later material has filled it in.
Is Xenosaga the Xenogears prequel?
No. Xenosaga is built on the Episode I concept, but rights problems meant the setting was taken apart and rebuilt rather than continued, so the two are not the same continuity. The concrete thing that settles it is the chronologies: the Episode I era timeline in Perfect Works and the Xenosaga timeline are a few years out of alignment. Zohar, Earth and the Wave Existence also work differently across the two. It is a remake of the premise, not a continuation of the story.
Will the other Xenogears episodes ever be made?
The most recent word is Takahashi's, from February 2018. Asked what had become of the six-part plan, he said he wants to resolve it at some point in his lifetime, and he has not expanded on it since. The obstacles are structural rather than mysterious: Xenogears belongs to Square Enix, while Takahashi has spent the last fifteen years at Monolith Soft building a different series for a different platform holder. Nothing has been announced.
