Discounts
Every price cut of more than 20% we have observed, in each market that quoted one, with this game's chart position on either side of it. These are episodes, not a model: a sale is one event, and one event cannot tell you what the next one will do.
Reviews, worldwide (the counter carries no country): 0.29/day in the week to Sep 4 → 0.86/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 24 chart moves that followed a price cut of more than 20% went a median of 9 places towards #1, and the 2,404 moves with no price cut behind them went 2 away. One store, one chart, one country — it is the only place we have enough observations to say even that.
Prices outside the United States have been collected since 6 August 2026 and chart positions since 19 July 2026, so a cut older than that has no market to compare and a market that joined later has no history yet. Nothing here is converted between currencies.
About
Kumitantei™: Old-School Slaughter is an episodic murder-mystery ADV cardbattler that lovingly fuses retro anime analog horror with killing game! Kumitantei will consist of 6 episodes, beginning to release in early 2026.
"The Empire of Japan, 1989... Awoken in a decaying old bunker, sixteen elite Absolute Students are trapped in a kill-or-be-killed Apathy Experiment. Will they band together to uncover secrets of this anemoic alternate past, or lose their humanity and lives in the present?"
With a visual style inspired by Rumiko Takahashi’s Urusei Yatsura and '80s anime alongside classic Japanese mystery-adventure games like Danganronpa and Ace Attorney, Kumitantei™ thrusts you into a suspenseful character-driven killing game narrative where your deckbuilding and detective skills are the only keys to surviving. It's a creepy-cute love letter to decades of ADVs that wears its many inspirations on its sleeve: perfect for fans of visual novels, detective games, and deckbuilders with deep narratives.
Bond with your classmates! Get to know the Absolute Class of '89 by listening to them, giving them gifts, and receiving powerful cards to use during debates!
Investigate grisly murders! Use your detective skills to comb through slain classmates’ crime scenes and take your evidence to trial!
Survive the trial! Cut through the lies and prove your case. Inspired by Ace Attorney and the cult classic Danganronpa series, Clinical Trials can only end in bloodshed, whether it's the culprit's or everyone else's!
Build your deck! Create absolute combos using cards you find in the Bunker and through bonding with your classmates to dominate the debates and trials!
Please insert coin! Test your retro gaming skills in a variety of faithfully crafted anemoic riffs on true old-school arcade icons!

remove those ♥♥♥♥♥♥ boring card minigames from the concept lmao
Es un muy buen fanganronpa la verdad, aunque no lo catalogaría solo por ser un juego fan de danganronpa porque tiene muchisimas mecanicas únicas que lo diferencian de este mismo aunque teniendo la misma estructura, las animaciones son muy lindas, el arte tambien, los personajes me cayeron bien y el primer capitulo me gustó mucho, espero poder ver más de este juego pronto.

没想到只有第一章，不过光第一章就有7小时游戏时间，总的来说比较好玩，原创角色个性很强烈，没有原型的弹丸论破系列的那种伪人感和怪味，作为推理爱好者很喜欢
this game feels like a gamble ngl while yes, some of the characters are entertaining and add flair to the game i feel like the actual flesh part of the game just feels like a watered down version of danganronpa the first case doesnt feel satisfying at all to solve, nor does it really give a good introduction to how the cases are going to move forward. plus the murder itself is a bit... wack. i really hope that chapter 2 can surprise me, because i really do like the idea of the game! wicked
I enjoyed playing the first episode of this game
This was a great start, I'm really looking forward to the rest of the game! All I would really advise is incorporating the card battling more, I know the devs are planning on adding them to FTEs but I think adding them to investigations would really make the investigation portions feel like their own thing, and not just a chore to get to the trial.
El cariño a este proyecto es enorme, las emociones que transmite con un solo capitulo es fascinante Si eres fan de Danganronpa DEBES de probar esto
I was very happy to find out that this exists. Looking forward to the rest of the episodes and other content
i love the conspiracy theorist hes an idiot
