Monster Girl Tactics: Oubliette is an erotic strategy RPG from Minolione, using the Others engine and a 3D presentation. You play a male protagonist who joins a rising mafia of ambitious monster girls in a fantasy setting, hunting for power, revenge, and change. The text-based story offers branching romance and consequential choices, while optional turn-based tactical battles let you recruit and equip a team. All text is handwritten by Minolione.
The current vF6-A build, released September 19, 2026, finishes Chapter 6 and development continues. It is available for Windows and Linux in English, with no censorship. This update adds performance settings, improves Brightness, and optimizes hub maps for better frame rates. It also lets players exit menus with right-click and opens Save/Load on the latest page.

Version [F6-A]
Finishes Chapter 6
Adds
new performance options
to the settings menu.
My laptop (i7-6600U, integrated GPU) went from
5 fps to 58 fps
in the first hub map.
If you previously put the game down due to poor performance, please give it a try with this update's performance settings!
Main Fixes And Improvements
Improved "Brightness" setting (now illuminates dark areas more).
If you're updating from an older game version, you must change and apply settings for it to take effect.
Optimize: Better performance on hub maps (i.e. not battles).
On my PC, I gained +13.8% FPS on the biggest map, but it depends on map size and PC bottlenecks.
Polish: Can now exit menus via right-click (in addition to Escape and the "back" button)
Polish: Save/Load menu now starts on the page with your latest save
Fix: Could softlock in Chapter 5 event under certain branching conditions
Fix: A certain character could be killed in a battle where that shouldn't be possible
Fix: Misleading "end chapter" on a choice
"Screenshake" slider now affects the red pulse/zoom effect in certain events
Change setting "Skip Seen Interludes" to be enabled by default. (Existing players won't have their settings changed)
Add toggle-sprint option (as opposed to hold-to-sprint). Settings -> Controls -> Hub -> "Enable Toggle Sprint"
Fix: crash to desktop after finishing the intro cutscene
It was caused by the game failing to acquire your system's timezone when autosaving
I have no clue why that failed. According to the time library I'm using, this operation should never fail (I am now using a different time library for this).
Also, once you view the intro cutscene, you can now skip the intro when starting another new game
Version [F5-A]
Adds the first part of Chapter 6
Main Fixes And Improvements
Add setting to skip mission-travel transitions
Fix crash upon using items that were half-equipped as a result of save file editing
Fix UI sometimes breaking if Mongo dies
Fix crashing on startup if
persistent_data.json
has been corrupted (due to e.g. crashing or closing while saving)
If it's corrupted, you'll be asked if you want to reset the file. Doing so will let you launch the game, but you'll lose certain data: memory scene unlock progress, achievement progress, and seen texts for 'Skip Unseen Text'.
From now on, I back up the file every time you exit the game. If the original is corrupted, I'll try restoring from the backup as an alternative to resetting it.
Version [F4-A] [September 10, 2026]
Updated Linux build with a smol fix. Not worth a version bump
Version [F4-A]
Adds all of Chapter 5
Main Fixes And Improvements
Fixed some locations where players can get stuck in a wall (and not in the lewd way)
Crashes: made another quick patch to the engine in an attempt to reduce sporadic GPU-related crashes
Also disabled (unused) engine code for gamepad controllers, to try to fix odd rare crashes involving that
Fix: text scroll/fade speed was slower than intended if your FPS was below 60 (it got slower the lower your fps was)
Improved how text fades in when a line is replaced/appended to
Version [F3-A]
Adds the rest of Chapter 4
Main Fixes And Improvements
Added setting to auto-skip interludes (mission-travel transitions and epigraphs) if you've already seen them
Crashes: Game will attempt to automatically recover from certain types of sporadic GPU-related crashes
Not a tested fix, since I can't recreate this issue on my own machine
To avoid toothy tragedy, Injured units will now heal after Hana's night crawl encounter in Chapter 1
Fix: Certain reinforcements could spawn after you had already won a battle
No longer need to jump to walk up the stairs in the caves (added invisible ramps)
Fixed Fast-Forward Mode speeding up the map playtime timer and messing up the "Time Elapsed" display upon winning a battle
Version [F2-B]
Hotfix update
Fixes the horribly broken UI on non-16:9 resolutions
Fixes the text scrolling out of bounds more and more as you progress through events
Version [F2-A]
Playable from the start up to ~50% through Chapter 4.

Absolutely wonderful, one of the best ero games I have ever played. Very good use of limited visuals, great music and the writing is amazing. I have only played Deiza route and it made me extremly emotional multiple times, I…
Celerarity2026-09-21★★★★★
This game doesn't seem like it should work, but it does. The characters are colored spheres but I care more about them than most recent games I've played. The visuals are all heavily pixelated but it still oozes style. The…

I don't usually write reviews, but this game deserves it. This might be the most quality H-game I have ever played. Everything in here is doing a lot with a little. Despite there being no portraits or CGs, there are…
