Shin Megami Tensei if… Guide: Complete Dungeon Maps with Coordinates for All 102 Floors (PS1 / SNES)

日本語版を読む →

Shin Megami Tensei if… is a strange beast within the Megami Tensei series. The setting isn’t Tokyo, and it isn’t the Expanse — it’s Karukozaka High School. A vengeful classmate drags the entire campus into the demon world, and the students find themselves trapped in dungeons themed on the seven deadly sins. That combination of teen-drama high school story and hardcore Megaten is exactly the line that would eventually lead to Revelations: Persona.

The heart of any playthrough is the partner you pick. Choose one of the four partners early on (Charlie, Yumi, Reiko, or Akira) and the dungeons you’ll actually crawl through change completely. The three main-route partners take you through six realms in sequence, from the Realm of Pride to the Realm of Wrath, while the Akira route sends you down a dungeon set all its own, from the Earth Nomos up to the Heavenly Nomos. Each route also ends differently, so a single playthrough will never show you the whole picture.

This guide is based on the PlayStation version (released December 26, 2002), and it includes coordinate-labeled maps for all 17 dungeons and 102 floors across both the main route and the Akira route. The coordinates line up with the “East ◯ / North ◯” system shown on the in-game automap, so if you get turned around, compare the automap against the coordinates on our maps.

I’ll be honest: I completely lost my sense of direction somewhere around B6 of the Realm of Gluttony. The floors spiral inward and get narrower as you descend, and even with the automap open I couldn’t tell whether I was heading up or down. The person these maps ended up helping most, it turns out, was me.

What kind of game is Shin Megami Tensei if…? The Megaten spin-off where a high school becomes the demon world

Shin Megami Tensei if… is a side story in the Shin Megami Tensei series, a juvenile RPG set at a high school. Alongside a partner, you work your way through demon-world dungeons built around the seven deadly sins.

The story takes place at Karukozaka High School. A classmate named Hazama strikes a pact with a demon lord and drags the entire school building into the Expanse. You play as one of the students left behind, and together with your partner you have to escape the demon-warped campus.

The game launched on the Super Famicom in 1994, right on the heels of Shin Megami Tensei II. As the “if…” in the title suggests, it’s a hypothetical: what if demons had appeared in everyday life, before Tokyo was destroyed? That concept carried straight over into Revelations: Persona two years later — a piece of series trivia that just about every Megaten fan knows by heart.

The dungeons are built as demon realms themed on the seven deadly sins (Pride, Gluttony, Sloth, Envy, Greed, and Wrath). By rights there should also be a Realm of Lust, but it never appears in the game. Each realm has gimmicks and bosses that match its theme: the Realm of Gluttony, for instance, is a structure that spirals downward, while the Realm of Envy is a maze of floors that repeat with near-identical layouts.

What’s different between the PS and Super Famicom versions? Dash, difficulty select, and added events explained

The PlayStation release is a port of the Super Famicom version, with a handful of additions that make it friendlier to play. The dungeon layouts themselves are completely identical to the original — no changes to wall placement or floor counts.

For anyone who played the Super Famicom version, the single biggest gift here is the dash. This game’s dungeons run 102 floors deep, and exploring all of that at normal walking speed takes real patience. On PS, R1 makes getting around dramatically less painful.

EASY mode’s unlimited ammo is seriously strong. On the Super Famicom, managing your remaining bullets was genuinely tight; on EASY you can spam gun skills without ever worrying about running dry. If this is your first playthrough, go with EASY — if you want the game to push back, take NORMAL.

One more time for clarity: wall placement, floor structure, and event placement are all completely identical to the Super Famicom version. The maps in this guide are built from the Super Famicom structural data, but they work just as well on PS.

What does your partner choice actually change? The four route branches and the Guardian system

The defining feature of Shin Megami Tensei if… is the partner system. You meet four students while exploring the school early on, and the one you pick locks in your route for the rest of the game.

Charlie, Yumi, and Reiko all send you down the same main route through the same dungeons. Story beats and endings differ, but map-wise the crawl is essentially shared. The Akira route, on the other hand, gives you an entirely separate set of dungeons — the Nomos — which effectively amounts to a second game’s worth of content.

What is the Guardian system?

This game has a Guardian system that would go on to become the prototype for Personas. The protagonist is assigned a “guardian spirit,” and it changes as you level up or through story events. The protagonist takes nothing but the stat bonuses from a Guardian, while it’s the partner whose learned spells are dictated by the Guardian. Both of them swap to higher-tier Guardians as their levels climb, so this feeds directly into how you build them.

The Alice event added in the PlayStation version lets you swap in Alice as a Guardian once you meet specific conditions. It’s an element the Super Famicom version never had, which makes it one of the PS version’s signature draws.

What Determines the Protagonist’s Guardian? All 16 Stages, Split by Gender

The protagonist’s Guardian is locked in completely by the three types (Power, Speed, Balance & Luck) determined by Nova’s opening question and your gender. Every time you hit the required level, the next Guardian takes over — and again, all the protagonist gets out of it is a stat bonus. The spell list never changes.

All 7 Rare Guardians: The Hero Types Tie Directly Into the PS Version’s Special Chests

Separate from the standard demon pool, there are seven rare Guardians. Law Hero and Chaos Hero in particular are the keys that change what’s inside the special chests in the Realm of Envy and the Realm of Greed.

For partners, whichever Guardian is attached becomes their spell list, full stop. In other words, whether a character ends up a healer or an attacker comes down to which stage you decide to stop leveling at.

Demon Fusion and Working With Your Allies

The combat and demon-ally systems follow the Shin Megami Tensei I and II playbook. Talk demons into joining you, then fuse them at the Cathedral of Shadows. Your party is the protagonist plus a partner plus demon allies (roughly four at most), and the partner is a permanent fixture. On the main route a boss is waiting in every realm of the Expanse, so the standard approach is to fuse up allies who can hit the weaknesses before you ever walk through the door.

How Is Spell Inheritance Decided in Demon Fusion? The Priority Order Is Completely Fixed

Whether a spell carries over through fusion isn’t luck — it’s governed by a fixed priority table. Healing and support “universal spells” can be inherited from anyone, while attack spells only carry over when the material demon and the fusion result share the same inheritance affinity.

All 17 dungeons walkthrough chart: full coverage of the main route and the Akira route

From here on, I’ve broken down the key points of every dungeon route by route. The coordinates match the “E◯ / N◯” notation used by the game’s in-dungeon automap.

How the main route plays out

Karukozaka High School (1F–3F)

This is the school section that opens the game. You wander the building from 1F to 3F, talking to classmates and triggering events, and this is where you lock in your partner. Make a full circuit of the classrooms, the staff room, the gym and the rest, and clear the events as they come. Enemies do show up, but they’re still weak here, so treat the exploration as free XP.

The Sealed Chamber

A single-floor area that serves as the doorway into the Expanse. Everything past this point is dungeon crawling for real, so check where your save point and your healing options are before you push on.

Realm of Pride (B1–5F)

The first Expanse dungeon. Six floors isn’t especially large, but you’ll be bouncing up and down between levels constantly. You start on B1 and work your way upward. Belial hits hard with fire, so bring a demon ally with fire resistance.

Realm of Gluttony (B1–B8)

An eight-floor monster of a dungeon with a distinctive spiral layout in which each floor is narrower than the last. B1 is the widest, and the map shrinks steadily as you descend toward B8. One-way corridors and warp zones are scattered throughout, so keep checking the automap as you go. Beat Orcus and you’ll find yourself heading somewhere new: inside Orcus.

Inside Orcus

A special dungeon you enter after Orcus swallows you whole. It’s only one floor, but that floor is big. You pick your way through a layout built to resemble internal organs, hunting for the way out.

Realm of Sloth (B1–B3)

Compact at three floors, but each of those floors is enormous — B3 in particular is a huge map with over 100 tiles of walkable floor. True to his name, Belphegor opens the fight with an asleep animation, but don’t let that fool you. Once he wakes up, the damage is brutal.

Realm of Envy (1F–6F)

A six-floor dungeon whose maps get tighter the higher you climb. Floors with near-identical layouts repeat, which makes it very easy to lose track of which one you’re on. Lean on the automap coordinates to pin down your exact floor. Leviathan specializes in ice, so an ice-resistant demon ally makes this a much smoother fight.

Realm of Greed (B1–4F)

A five-floor dungeon. 1F is the biggest at a sprawling 222 tiles, then the maps contract fast as you ascend — 4F is a mere 12 tiles. This area is stuffed with treasure chests, and in a place called the Realm of Greed you can guess how many of them are trapped. Mammon’s multi-hit attacks are the real threat here.

Realm of Wrath (B2–3F)

The toughest dungeon on the main route. It’s split across nine separate maps, with B2 alone weighing in at 256 tiles. B1 and B2 are divided into west and central sections, while 1F breaks into four pieces — West 1, West 2, Central and East. You’re hopping between maps constantly, and it’s brutally hard to hold the whole thing in your head.

The trick is to start at B2 and climb methodically. Map out the staircases on B2’s huge floor, pass through B1’s A (west) and B (central) sections, sweep the areas of 1F, then push on to 2F and 3F. Satan ranks among the strongest of the main route’s sin-lord bosses, so go in fully prepared.

Karukozaka High School: Upper Floors (4F–11F)

Once you’ve conquered all six realms of the Expanse, the game takes you back to the upper floors of Karukozaka High School. 4F and 5F are gigantic 256-tile floors; from 6F up the maps narrow rapidly, and 10F (12 tiles) and 11F (10 tiles) are essentially single corridors. This doubles as your prep stretch before the final battle with Hazama, so get your party sorted at the Cathedral of Shadows.

The Mental World

The final dungeon: one sprawling 240-tile floor, and the stage for the last showdown with Hazama. Your ending depends on which partner you picked, so every choice you’ve made up to this point pays off right here.

How the Akira route plays out

Earth Nomos (B10–1F)

The Akira route’s opening dungeon, and a long haul: 11 floors climbing from B10 all the way up to 1F. Individual floors are fairly compact at roughly 60 to 80 tiles, but there are so many of them that the total workload adds up fast. The whole structure is about clawing your way up from deep underground to the surface, so finding the staircases is the core of the crawl.

1st Nomos (1F–6F)

A six-floor dungeon that climbs from 1F (inner section) to 6F. That 6F is a 256-tile behemoth and the hardest part of the 1st Nomos, since you have to hunt down staircases and events across a genuinely huge map.

2nd Nomos (6F–14F)

A mid-sized nine-floor dungeon running from 6F (after the Tapeto revival) up to 14F (inner section). Floor sizes are relatively consistent at around 54 to 63 tiles. A major story beat, the Tapeto revival event, lands partway through. 14F is a large 144-tile floor and your connection point to the 3rd Nomos.

3rd Nomos (14F–24F)

The biggest dungeon on the Akira route. It runs 11 floors and the floor sizes swing wildly: 14F and 24F are large 144-tile affairs, while 21F is a wide, shallow 48-tile layout, and so on down the line. It’s clearly designed to keep things from getting monotonous, but the flip side is that it takes real time to get a read on each floor’s quirks.

4th Nomos (24F–29F)

A six-floor dungeon. 24F is 144 tiles and 25F and 26F are 112 tiles each — a run of mid-sized floors that gradually tapers down to 64 tiles on 29F. This is also your last prep stretch before the Heavenly Nomos, so get your fusions done here.

Heavenly Nomos (30F–37F)

The Akira route’s final dungeon. It’s eight floors, but only 30F and 31F are mid-sized at 63 to 64 tiles; from 32F onward it’s a string of tiny 16-tile floors. The maps contract sharply as you near the top, and on 37F you face the Akira route’s final boss. The PS version adds new music to this route, so the last battle carries a different atmosphere than it does on Super Famicom.

Five places players tend to get stuck

① Your partner choice is permanent

The partner you pick early on can’t be changed later. Choosing Akira in particular locks you out of the main route’s dungeons — the Realm of Pride through the Realm of Wrath — entirely. Conversely, the three main-route partners never set foot in the Akira route’s Nomos towers. If you want to see every dungeon, you need at least two playthroughs. For a first run, I’d go with Charlie or Yumi and soak in the main route’s classic arc.

② Getting lost in the Realm of Gluttony’s spiral

The Realm of Gluttony is a spiral in which the floors get narrower as you go down, shrinking in stages from B1’s 64 tiles to B8’s 16. The problem is the one-way corridors scattered along the way, which constantly leave you unable to backtrack. Watch the automap coordinates and always know which level you’re standing on.

③ The Realm of Wrath’s fragmented maps

The Realm of Wrath is carved into nine separate maps. B1 splits into A (west) and B (central), and 1F splits four ways into A through D — a structure the automap alone will never make legible. Keep this article’s maps open beside you and check which area you’re in as you move.

④ Don’t underestimate how long the Akira route is

The Akira route runs 51 floors, putting it on par with the main route in sheer bulk. Earth Nomos alone is 11 floors, the 3rd Nomos is another 11, and the long slogs just keep coming. Unless you plan your MP usage and your fusion roadmap for the long haul, you will run your resources dry somewhere in the middle.

⑤ Missing the window when your Guardian changes

Your Guardian can change when you level up, but the conditions are convoluted and landing the specific Guardian you want is genuinely hard. The PS version’s Alice event gives you some measure of control, though you’ll need to look up the trigger conditions in advance. On a first playthrough, the realistic approach is not to overthink it and simply roll with whatever Guardian you naturally end up with.

Can You Play Shin Megami Tensei if… on Modern Hardware? A Complete Platform-by-Platform Guide

① Titles playable via subscription or for free

The easiest way in is the Super Famicom version on Nintendo Switch Online. If you’re already a subscriber, it costs you nothing extra. The SFC release lacks the PlayStation version’s dash and difficulty select, but the dungeon layouts are completely identical — every map in this guide works as-is.

② Titles available to buy individually

If it’s the PlayStation version you want, the download release on PS Archives for PS3, PSP and PS Vita is your option. Go this route if you want the benefits of the PS version’s dash and EASY mode. An iOS version exists too, but check device compatibility before you buy.

③ Titles playable as a remaster or remake

As of September 2026, no remaster or remake of Shin Megami Tensei if… has been announced.

④ Titles that are hard to get on current hardware

Physical Super Famicom and PlayStation copies are only available on the secondhand market. There’s no real need to chase the SFC cartridge when the game is on Nintendo Switch Online, but if you insist on the original PlayStation disc, you’ll be hunting used. Even then, the PS Archives release is still purchasable, so the PS version remains available digitally.

If you’re already subscribed to Switch Online, the SFC version is the easy way to dip in. And if you start missing the PS version’s dash, switching over to PS Archives is no problem — the dungeon layouts are exactly the same, so the maps carry straight over.

Summary: Shin Megami Tensei if… Is the Origin Point of “School Megaten” — and a 102-Floor Labyrinth

Shin Megami Tensei if… (PlayStation version) launched from Atlus on December 26, 2002 as a port of the Super Famicom original (October 28, 1994), adding difficulty select, a dash function, the Alice event and more to make it the definitive edition. The dungeon layouts are completely identical to the SFC version, and the game boasts a staggering 17 dungeons across 102 floors.

The heart of the game is your partner choice. Pick Charlie, Yumi or Reiko and you’ll travel the Expanse’s seven deadly sins on the main route (51 floors); pick Akira and you’ll tackle a unique set of dungeons called the Nomos (51 floors). Both routes run past 50 floors, and your partner also determines which ending you get.

On modern hardware you can play it either through Nintendo Switch Online (SFC version) or PS Archives (PS version). Given that this game’s concept — a demon-summoning RPG set in a high school — was carried forward into Revelations: Persona, it’s a title Persona fans in particular owe it to themselves to play.
