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 26 chart moves that followed a price cut of more than 20% went a median of 7 places towards #1, and the 2,400 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!

Reviews
就弹丸类型的模仿作来说，算是中规中矩的作品。基本保留了弹丸主要的游戏要素，卡牌小游戏的设定有可取之处，人设也符合弹丸那种夸张鲜明的风格，制作组自设的另类世界观目前看来和剧情伏笔应该有诸多联动之处，对苦苦等待2x2的弹丸粉而言作为代餐入手不亏。 优点说完了来说缺点。第一案难度不大，然而太多信息是在学裁中才能获悉的，仅凭搜查阶段的线索很难推断出凶手身份。另一方面被害人的人设在案件前和案件中变化太大，没有很好体现在日常的伏笔里。更甚的是，日常剧情之中相对于交流和情感培养，人物之间重复性的对抗和吵架太频繁了，看得实在是心累。真让人感觉这个实验完全没必要做，这帮家伙一开始不就已经是冷漠的代名词了（笑）学裁那部分的中文翻译还有一些低级的逻辑错误，比如某句话应当是“今天审判的就是我被谋杀的案件”而不是“我作为谋杀犯站在审判席上”。希望后续更新中可以更正。 最后是个人性质的吐槽，制作组不知道为什么特别喜欢玩jumpscare这一套，然而弹丸正作主打的是荒谬的处境下绝望和希望交织的对抗和挣扎，而不是用突然出现的图片给玩家制造惊吓。这点从黑白熊剧场采用怪诞滑稽的风格可见一斑。制作组可能认为恐怖和死亡游戏的绝望感更为搭配，但是恐怖的感觉是官能性的，而荒谬的体验是精神层面的，本作在后者方面还是欠缺不少。当然，这也可能只是我个人的审美偏好，而且我本人真的特别容易在自以为非恐怖题材的游戏中被jumpscare吓到半死（笑）。期待制作组后续章节能够越做越好。
one of my friends recommended me this game and i figured i'd give it a shot. this game is incredibly charming, the card game/combat system is really cool, and i really enjoy the characters. my favorite is hiroshi. at the time of me writing this review, only the first episode is out, and i am really looking forward for when the next one drops!

Actual emotional rollercoaster..... Never been so invested in a game and i CRIED for the first time while gaming. good job kumitantei :sob:
this game may only have one chapter right now omg its so good im crying, sobbing, eating my tears even im going to be very happy for chapter two
Such a good game- can't wait to see where the story goes from here! Extremely well made- the voice acting and animations were a pleasant surprise for me! :)
Originally went in with low expectations, but this game surprised me in every way. From story, characters, gameplay, audio and visuals; it's all excellent. I really enjoy the art style for this game, as well as it's setting. I came to enjoy the card battles after learning how it all works. The horror aspect while not very prevalent, is something I eventually started to like. I hear it will be more significant in future episodes, which is exciting. What really had me hooked was the soundtrack and characters. All of the characters are great in all ways, like visual design, writing and voice. Major props to the voice actors, they are very talented. The soundtrack is exceptional, especially the main theme used for the opening movie. I don't really have any criticisms or complaints, but they appear to be very onboard with feedback so I imagine future episodes will be even better than what I already enjoyed with just Episode 1. The fact it's not fully released might deter some for now, but I truly believe it will be completed in a reasonable time. Massively recommend this game to anyone who enjoys death game visual novels, like danganronpa or your turn to die. This review is pretty vague, but I wanted to avoid specifics and just generally say I was impressed with what kumitantei had to offer.
Одна из лучших фанронп на данный момент. Анимационные вставки между диалогами, приятный интерфейс и оч крутой ост, да и сюжетка хороша
Two complaints so far is I scrolled up and got stuck on the New Game on the start menu and the auto save feature. I exited the game and the cursor got stuck on new game qnd I accidentally hit it and it overwrote the save from the beginning when I got a few hours in.
PLAY THIS GAME PLAY IT PLAY IT PLEASE PLAY IT PLAY IT PLEASE PLAY IT.
jogo muito bom, animações bonitas e uma história coerente
