Hidden Badge is a game made by Night-Day-Night-Nine in Unity. It uses animated artwork and a sandbox structure with turn-based combat. You play Ryoji, a former Public Security Bureau agent who left after being falsely accused following his partner's death while investigating the Scorpion gang. He returns as a False Badge to find the truth. His PSB classmate Rinn supports him, while corruption links the bureau to political and economic powers. Rinn's younger sister Yaoyin becomes drawn into the case, and Ryoji's old friend Kaiza offers help that may hide trouble.
The current build is v20260929, released on September 29, 2026. Development is ongoing. It runs on Windows, is written in English, and is uncensored. The latest changelog says Takiyo's relationship route begins, while Rein's story enters its final acceleration phase, so both routes will progress together. The changelog notes missing animations for a later update. The creator also says next month's Demo update is skipped so more CGs can be finished for Rein and Takiyo.
Developer's description
The protagonist Ryoji, once an Agent of the Public Security Bureau (PSB), was forced to resign after being falsely accused following the mysterious death of his partner during an investigation of the gang “Scorpion.” Determined to uncover the truth, he dives back into the criminal underworld as a False Badge.
Spoiler
Joining him is his fellow PSB classmate Rinn, a cool-headed and disciplined Agent. In a web tangled with power, betrayal, and desire, she becomes the only one Ryoji can truly rely on.
As their investigation deepens, they uncover not only evidence of crime but a massive network of corruption tying the PSB’s upper ranks with political and economic forces. Meanwhile, Rinn’s younger sister Yaoyin becomes entangled, exhibiting increasingly strange behavior—her presence even surfacing on illegal platforms. Though she denies everything, Ryoji knows her freedom is slipping away.
Adding to the tension, Ryoji’s old friend Kaiza plays a shadowy role. While offering help on the surface, he increasingly meddles in Rinn and Yaoyin’s lives, making it harder for Ryoji to tell friend from foe.
In this convoluted struggle, Ryoji has only one option: move forward. Even if it costs him everything, the truth must be unearthed, and corruption exposed.
v20260929
The missing animations will be added in a later update.
Story Progress
Takiyo's relationship route officially begins with this update.
At the same time, Rein's story is entering its final acceleration phase, which means both of their storylines will be progressing at the same time from this point onward.
And that creates a very straightforward problem—
The next update will require CGs for both Rein and Takiyo at the same time.
As a result, the number of CGs that need to be completed for the next batch is significantly higher than usual. To avoid rushing the artwork and slowing down the overall story development,
there will be no Demo update next month
so I can focus on finishing this batch of CGs first.
CG production itself will continue as usual, so
Core members will still receive their regular image updates.
The animations that couldn't be completed this time due to the outsourcing issue will also be added next month.
So while there won't be a new Demo next month, development itself will continue as usual.
Known Issue
After making the final build, I noticed that
the original melee attack is currently missing.
I've already confirmed the issue, but it doesn't have much impact on the game and won't prevent you from progressing through the main story. Rather than delaying the release further because of this, I've decided to release the current build first so everyone can play it.
This issue will be fixed in a future version.
Bug Fixes & Changes
Fixed an issue where the game could freeze if the player entered another battle after being defeated.
Fixed the battle UI displaying incorrectly at certain unusual resolutions.
Fixed the resolution settings. Selected resolutions should now apply correctly.
v20260828
v20260729b
v260629
This update adds two more days of the main story and officially begins Takiyo's romance route.
I originally planned to finish the Love Route in this update as well, but while testing I found several branching issues. Because of that, the next update will focus on fixing bugs related to the Love Route instead of advancing the story timeline. If everything goes as planned, it will also include a new Love Route CG.
I'm also not very satisfied with the current combat system. Right now, battles mostly consist of both sides trading hits until someone wins, which isn't very engaging. The next update will address the known combat issues and improve the overall battle flow.
One more small addition: Love Route CGs will not appear in the chatroom. (I don't think the protagonist is the type of guy who would upload photos with his girlfriend to an adult forum.) Because of this, I'll be adding a Gallery feature so you can review unlocked CGs without relying on the chatroom.
Known Issues
Chatroom videos may occasionally become unclickable. Opening and closing the pause menu usually fixes the issue.
Mouse movement on the map still feels a bit awkward.
Saving may occasionally fail. Please check whether the save slot has actually updated.
Some combat features required to distinguish the Love Route are still missing, so the Love Route remains temporarily locked.
The animation didn't make it in this time. It'll be added in a future update.

I liked it despite the bugs, Bugs are expected as its a WIP game. I saw the rating is below what it deserved so gave it 5 star to improve the rating. My review should end here but F95 system…

Solid game with a decent amount of content. The sandbox feels very move from point A to point B, but the animations make up for it. Art 4/5 Sound 4/5 Gameplay 4/5 Would highly reccomend play, especially if you are…

Can't really recommend currently. Running into a bug on the second mission that breaks the game. After the robbers flee and Kaizawa takes Rein I can't find the object to pry the door open. Talking to the other person doesn't…
