Mod installer and public mods

This took WAY longer than I expected, but here it is.
InterAction Mod Installer (aka IAMI) can install mod files made by our Discord modding team for any game made by InterAction studios known at the moment. It was tested with most game versions and is pretty stable but installation process is slow so I’ll be re-writing it from scratch later to improve performance. For now just keep in mind you can start installation and go drink some tea :tea: (average speed: 10 files per minute).

So, how can you use it?

  1. Download IAMI and the latest CIU.iami file from here and extract them anywhere you want to (it’s better not to use system folders like Program Files as they require Administrator permissions).
  2. Download mods you want. You can install several mods one above another, the last mod installed will only change files it needs to. NOTE: backup is created based on the files before modding, so if you install several mods, backup will contain previous mods installed.
  3. Open IAMI and follow instructions (select a mod file, select a file in the game folder, confirm installation).
  4. Wait till the worst algorithm in universe finishes it’s non-optimised job. DON’T open the game while installing mods. Both game and IAMI won’t like it. You can do whatever you want during installation.
  5. When installation is finished, you’ll hear a signal so you won’t miss it. Just close IAMI after it, either by pressing Enter or closing the window.

How to uninstall the mod

The tool modifies the CIU.dat.hq2x game file and creates a backup of it before doing anything every time you install a mod. To uninstall the last mod, remove/rename current CIU.dat.hq2x and replace it with CIU.dat.hq2x.backup (do not forget to remove the .backup part of the name). It works as long as you don't disable full backup option in configurations file.

There is a problem when Windows Defender recognizes my stuff as a virus. I can assure you it’s not as it’s my 2nd C++ project and I have no idea how to write viruses мояй_discord_emoji Fixed in the latest update.

Please note that CIU only accepts CIU mods files for several reasons I can’t avoid. Also, CIU.iami file must be in IAMI folder in order to be found and work properly.

If you encounter a bug or have mod suggestion, write it in this topic so people responsible for mods can see it. If suggestion worths it, someone will make a mod file for you. You can also ask about it in IAMI Discord server.

UPD: Too many updates here so put all in spoiler (last update: 16th of January, 2021)

UPD: @ScarletCuboids Made an IAMI Discord server where you can also discuss, get or request some mods. They often appear there faster than here so join if you’re interested.
UPD in UPD: Ramon left his server but it’s still working.

UPD2: As this topic got closed and I don’t see any serious reason to unlock it, use the Discord server from above to request mods.

UPD3: My school project is near to completion and now I’ve started working on complete rewriting of IAMT and IAMI from scratch to make them faster and maybe more cool-looking (no GUI tho, still learning this part). Also I’ll make an attempt on replacing functions which trigger false antivirus warnings (yes, I’m fighting with antivirus too). The only thing I can recommend for now is to make manual scan of .exe and with high possibility antivirus will say it’s safe. This update will be useful not only for those who use mods but for those who create them too: rewritten tool will allow to put some functionality I couldn’t add before for code crowdness reasons and speed of repacking files in IAMT will be even higher than IAMI (currently IAMI is twice as fast as IAMT, so now you know why we don’t share it to public: it’s annoying and not clear to use. People who ask for it just won’t be able to do anything with it).

Updated version of my original mod, now with every music track replaced with Lobotomy Corporation/Library of Ruina soundtrack except for the CI1 theme because no song in the world is worthy of replacing it. (and darkness theme is now more spoopy :] )

The Lunar Capital Expedition

By @ScarletCuboids

Recruit #8775 found something on the moon. It’s some sort of city, technology there is way way more advanced than us. The UHF decided to launch an expedition mission. Little they not know, The Henpire already invaded the moon place…

This mod replaces the CI3 background with Lunar Capital from Touhou Project. Perfect for frozen missions. However, due to color, this mod is somewhat a disadvantage because of the bright color, clashing with the other colors, blocking your vision or some shit. It also replace the hyperspace with “Kaian Passageway” (Touhou 15 lore story shit idk).

DAlien Oofbreak 3: Invasion

By @Dawid8

Trailer: DAlien Oofbreak 3: Invasion Trailer - YouTube

The CD" is back, and it wants revenge. Will you figure out who truly stole the pizza and entertain the narrator, or is Earth doomed?

This is a mod for Chicken Invaders 3 Remastered. Its a sequel to my other unreleased mod, called DAlien Oofbreak 2: Invasion which was made for Alien Outbreak 2: Invasion.

It replaces a lot of the sprites, all music, and some of the sounds and it has been designed to be silly.

Download: Link

Note: The public release of the mod doesn’t contain the text changes present in the trailer.

Touhou Playable Danmaku Pack

By @ScarletCuboids

Normally I would bring this in the IAMI but I’ll put the weapons in the libraryinstead. These are danmaku bullets, they were originated from the Touhou Game series over hundred years ago. Now here, these are the danmakus. We have upgraded, enhanced and empowered so it could fit your spacecraft guns. These are the weapons:

Ion Blaster → Spirit Beater

Used to be a weapon owned by a shrine maiden who have retired. Now weaponized, dealing more physical damage more than ritual. The paper melts upon contact, stinging your enemy.

Neutron Gun → Enhanced Magic Missiles

Used by a magician who lives in a forest. Now a deadly weapon against evil Henpire. Totally Awesome.

Utenstil Poker → Throwing Knifes*

Used by a maid of a household. These silver throwing knives are able to weak your enemy with a single stab. And with many of them…heh…they don’t stand a chance *the Engrish is intentional, it stands for Firepower.


  • This is the first version of the mod so it’s not the best. I will remake it when I could
  • The bullets are just ripped from the touhou games. Probably will be drawn by me in the next version (or at least, tracing it)

Yes. You can ask for a mod which replaces any sound with anything, even music.

the readme is supposed to be read so k


This works with the older games too, right?

Very simple mod idea - a port for the low-alpha version of Positron from CIU into CI4/5. Simple enough to do where this tool isn’t really necessary, but it’s a small QoL thing that I’m sure non-modders would appreciate.

It even works for piggly and CI1 which was not intended.


A Utensil Sprite Swap for the Ion Blaster in CI1 could be fun, lol

(To be super clear, these are all just idle suggestions tho - I’m not “requesting” mods like I’m sure people will start doing soon, aha)

A question, Is there any risk when using this mod?

Well, mod file can be corrupted sometimes if we put wrong files in mod and this can break the game, but you can always restore backup of your hq2x as IAMI saves it near original by default. You can turn backups off in config.


Question - If I have a manually modded version of a CI game, should I revert it to vanilla before booting IAMI the first time?


how to use multiple mods? why i cant select like 3 mods at the same time

It’s better to do so if you used QuickBMS with files HIGHER than original ones, but if you didn’t, it should work just fine.

@peterexited You can. Just install one above another.
