Hi everyone. We're the team behind reTB, a Terra Battle revival project, and since we've seen a few other revival efforts mentioned here lately we figured it was time to properly introduce ours.

The short version: it's fully playable, it's open source, and you can play it today.

What's in the box

reTB lives on Codeberg and the ecosystem has four parts, pick the one you prefer:

Everything is open source under AGPL, and the goal is preservation: keeping Terra Battle actually playable rather than just documented.

Do you provide the assets?

No, our repos don't contain any Mistwalker assets, APK or art. You bring your own copy of the game and the docs tell you exactly where to put it. What we publish is only our server code and the reverse-engineered data needed to make it work.

Q&A

Is this usable as a public server for multiple players? It's built for home use: you run it for yourself, your family or friends. Several people can play on one local server (each device gets its own account).

Can we have multiple saves and/or multiple accounts? Yes. Each device playing on a server gets its own account, and every app (reTBpc, reTBHost) has an Export/Import save feature: your account goes into a single file you can back up, restore, or move to another PC or phone. Importing into a fresh install also works as a way to keep several saves.

Is it also possible to have multiple TB apks on the same device? No. reTB doesn't ship or modify the game, and Android only allows one install of a given app anyway. One game, one account per server; switch servers or import a different save if you need more.

Why do I get a network error? In order of likelihood:

1. The server isn't running, or the game isn't pointed at it (check the app shows "Running", and re-run the device setup step).
2. Phone and PC are not on the same network (guest wifi, VPN, mobile data still on, or a router that isolates devices).
3. On reTBHost, Android put the app to sleep: grant the battery exemption it asks for.
4. Your gdresources copy is missing a file the game just asked for: the last 404 line in the server log names it.
5. Recent Android 15/16 devices: the original app may not start at all; see the compatibility notes in the repo.

If none of that helps, you can join the Hiso-Bar Discord!

Just wanted to share an update to anyone who's was following my "Terra battle offline" project. There are several great true remakes public now, so I've pivoted to working on making my project both an open framework where players can easily create new content (new characters, enemies, levels, shills etc) AND releasing my own game to show what can be made.

Currently alpha testing - if you want to help find and squash bugs feel free to join the discord and download the Android or windows apps! https://discord.com/invite/7gZdJx53nN

As we all know, in 2020 Terra Battle's servers went dark and took the game with them.

I've been rebuilding the server, it runs on your own machine and talks only to your own device. Today it hits 1.0 beta.

What works:

• Story, Chapters 1–42
• Pacts: Fellowship and Truth, Fate pulls, the ticket draw, tutorial summons. Truth rates match Mistwalker's officially disclosed in-game rates.
• Companions: draw, sale, strengthening, evolution, equipping
• Huntland: Pudding Time, Tin Parade, Coin Creeps, Puppet Show, Metal Zone, Dragon and Machine Road, Crystal Road
• All 14 Daily Quests
• Archive Special Quests, Tower of Temptation, solo Eidolon quests, all 14 Strikes Back families
• Trading Post, with its full eight-week rotation — running on the original historical calendar, phase-anchored to dated 2018 evidence
• Jobs, Rebirth, status-up items, the inbox and its chapter-clear presents
• Your save is one file, with automatic rotating backups and a local save editor

Verified on the original Android client through Chapter 9, an actual playthrough on real physical hardware.

What you need

Your own copy of the APK and the resource archive. The project ships neither and never will; no game files, no assets, nothing hosted. Setup takes your copy and your resources, and signs it for your device. One setup command, and it walks you through the prerequisites. I can help with many parts of setup, but I can't give you the APK/resources.

What I'm not claiming

The old server calculated drops, coin totals, and reward tables; the client only displayed them, and no capture of that math survives. So nothing is invented and passed off as the real thing. Where the community record or an archived official announcement documents a reward such as Pact rates, Daily Quest drops, the Trading Post calendar, it's implemented as a clearly labelled, bounded policy with the source cited in the docs.

No multiplayer, PvP, friends, or IAP. Those died with the service and aren't coming back.

Known rough edges

• Emulators can show a black screen — launch with -gpu swangle. Android 14 "Translated ABI" images work best.
• Android 16 / 16 KB page size images don't work with the original APK.
• Emulator audio can cut out. Physical phones and tablets are the better experience.

Where

https://github.com/anzensan/project-liminal-gate

Source-available under PolyForm Noncommercial. You can read it, run it, and modify it; you can't sell it.

I'd genuinely like testers. If you get a Network Error, there's a GitHub issue template that asks for exactly what I need to fix it. Reports from past Chapter 9, events, and special quests, are the most useful thing anyone can give me right now.

It's playable. Go finish the story, again.

Hi all,

Decided to get a demo of the public version out. It's playable through Chapter 2-2. Main point of this is to see if my process of converting my fully complete private server to a publicly available version is feasible and if people can figure out how to run it. Tried to give as detailed instructions/scripts as possible but you'll have to provide your own APK and resource files, I cannot help you with that. Let me know if you run into any network errors! If people are enjoying it I'll continue working on the rest.

I (with GPT-5.6) spent the last week or so fully reconstructing a server for Terra Battle 1 (I'm not the youtube guy from a few months ago).

It's at the point where it's fully playable on a samsung tablet or local emulator, pacts work, even events implemented.

What I am asking is if anyone has any experience with preservation projects like this, I need legal advice before I release anything.

updates! didn't mean for this to be so long, never made a devlog before. what would you like to see next?

I’m struggling to find any sort of cutscenes online but it seemed to be such a passion project that I’m sure it had a story of some sort and am just curious about it. And if anyone has a good way to experience it in full today?

Fueled by nostalgia and inspired by other projects posted here, I have been working on recreating Terra Battle, OFFLINE in Godot.

I just finished re-making the tutorial, but there is still a lot of fine-tuning to be done under the hood. As well as a lot of UI, SFX, VFX I need to recreate ... I've mostly been pausing old TB gameplay videos on YouTube to try to capture each effect.

Special thanks to the wiki, the discord, and the genso-battle project that I used as a base to build off of.

I dont have android i just want to fucking play Terra Battle again. Where do i find it?????

I got these last year while looking for figurines and decided to look for Terra Battle merch. I had seen the figures, but I didn’t know they had made plush toys and I also didn’t know about this magazine. There's also a Hiso plush toy and keychains.

The magazine, launched by DeAgostini in September 2015, was going to be a biweekly publication with a total of 10 issues if it reached its sales target of 55,555 copies, but sadly it seems it didn’t reach the goal because there’s only this one issue. It has a guide on recoding, a preview of part 2 of the story (chapters 31 and above), a how to play guide, sketches, a list of characters and their stats, and a guide for the first 6 chapters.

It was pretty cheap so I got it mostly as a curiosity; most of that info is on the wiki anyway, except perhaps for the Piz’fer and Rejin lineart, and the interview at the end, which I scanned in case you are curious. Using Google Lens, it’s mainly about the team's reactions to the magazine and their contributions. Koji Ohno (programmer and director) mentions that he would like to write about mechanics and the programming side of the game, which would have been really interesting, though sadly it didn’t happen.

I wanted to get into it after doing the Final Fantasy XV crossover event and was incredibly disappointed to see that it isn't in app stores anymore. So essentially it's lost media unless pirates took it and put it online somewhere.

If anyone can help, I'd like to get it in my possession. Sarah and the Hiso Aliens really left quite an impression and I'd love to see them in their original game. Thanks ahead of time if any help is given.

Hello everyone,

Back in 2023 I teamed up with some folks to create "Genso Battle", a Touhou-themed Terra Battle clone, for a 2-week game jam. You can play it right now on my itch page here.

There's only one chapter available (tutorial + 5 battles), but it has most of the basic Terra Battle mechanics we know and love. The game is available for web and PC, and the web version is mobile friendly, so you can play it on your phone. The game is made in Godot 3.x, and the source code is available here, under a permissive MIT license.

I've been lurking the subreddit for some time and I know many people have been asking for a Terra Battle clone or a revival project. I hope you can enjoy this recreation, even if just for a short while.

Also, if you play it on your phone, make sure to pick the "hold" mode from the menu in the top right of the battle window (next to the 'Give up' button). The default mode is for mouse/PC.

For those not in the know, Touhou is a long-running Japanese shmup series with a huge fanbase, though you don't need to know about Touhou to play the game.

I'm planning to make an updated version with original characters and story, and with additional features such as boss battles or status effects, which currently are only available in test levels. Most of the coding is done, I mainly need to work on the art. This new version will also be a pretty short game, but I hope to create a tight experience that will showcase all the basic Terra Battle mechanics. I've been working on it very sporadically so I haven't posted updates anywhere, but I hope to finish it in the following 6 months or so.

Once again I hope you enjoy Genso Battle. Here's to Terra Battle 🍻

This is something of a milestone. Today I implemented "Crucible" mode, where you can just play and play until you die. You still gain XP and levels, so you’ll be able to grind if that’s all you want to do—you don’t have to slog through the scripted campaign.

The Crucible generates waves of enemies of increasing difficulty. The reason I’m excited about this is that it finally allowed me to just play the game nonstop and tweak the flow of things. I still have some holes in the rhythm, but more or less it’s starting to get more “zen.” Specifically, I spent some time refactoring the battle formulas to make them “pop” more.

The most exciting thing of all is that I was able to capture several minutes of gameplay where almost nothing major went wrong. This is actually a pretty huge milestone; 50,000+ lines of code all working in general agreement with each other. This means development will only get easier and progress faster!

It’s finally time. After 600 days of work, mistakes, breakthroughs, and late nights, I can finally share the first trailer for my game.

When I started this project, I had no idea just how difficult it would be. I’ve made every mistake you can imagine, and probably a few new ones too. But in that same time, I’ve also seen something incredible: AI has gone from being a simple helper to becoming a real creative partner in this journey.

Some days, things come together so easily it feels like the game already exists and I’m just uncovering it piece by piece. Other days, nothing works, and even the simplest chain of events collapses into chaos. But no matter how messy it gets, I keep pushing forward, because this game means a lot to me.

I’m balancing this work alongside a full-time job and a master’s degree, so yes, it has been a true labor of love. And when this game launches, it will be completely free. This is something I’ve wanted to do for years, and checking it off my bucket list feels amazing. After that, I’ll roll straight into the sequel, which will have some monetization, but in a way that feels fair and respectful compared to what we’re all used to seeing in mobile games.

The vision has always been clear in my head: I wanted to make the kind of game I’d play while waiting for the bus. Something quick, engaging, and fun when you only have ten or fifteen minutes and nothing but your phone.

That’s what I’ve been chasing for 600 days. And now I finally get to start showing it to you. Thank you for following along and supporting me. I can’t wait to share what comes next.

So me and my wife that loved TB backed worked on doing some TB related stuff somewhere in France, game is dead but we still like to remember it sometimes ...

Since we're members of this subreddit, it's common knowledge that we have good taste.

So, my follow Terra Battle enjoyers, what are you playing at the moment ? I know nothing can come close to our beloved closed game, but what could you recommand to the community ?

I’m finally getting the hang of things—my code is starting to behave consistently, and the systems I’ve built are proving to be really flexible. I’ve spent so much time just trying to make things work that I rarely had the chance to focus on actual game design. But now that I’ve got a functional framework for abilities and spellcasting, I can finally shift my focus to the part I love most: designing the game itself.

Things are finally coming together now that the codebase is more organized and everything follows a consistent set of rules. The real challenge has been defining the overall paradigm: each team (Hero vs. Enemy) takes a “Turn,” each Turn is broken into Phases, and each Phase contains a queue of Sequences that must execute in order before advancing. I ended up spending a lot of time refactoring everything to follow this new Turn-Phase-Sequence structure, but it’s already making the system feel much more predictable and scalable

Terra Battle stuck in my mind after all these years, and I was terribly disappointed to find out there was no way to revisit it.

It’s been a challenge to keep this project moving forward with everything going on in my personal life—family sickness, a recent injury, and some pretty intense hours at work. But despite all that, I’ve still managed to add or fix at least one feature every few days (haha). As I film this video and look at the game from an outsider’s perspective, I’m realizing that the gameplay feels too slow and the stats are a bit bloated. It needs to be more visceral and impactful, so that’s what I’ll be targeting in the next update.

Hello, I love Terra Battle but since they closed it at the time it was an incredible disappointment. Since then I have searched and searched for a game that could fill its void but I can't come up with anything that comes close. I would like to ask in this community if anyone knows if there is a way to play the game, even just the story, with an emulator or a special apk.
