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 2,402 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!

buen inicio, recomiendo comprarlo ahora y no despues ya que subira de precio
Есть потенциал, учитывая идею с картами Я даже кайфанул от игры
Beat for beat Danganronpa. Thought it may be a bit more subtle, but nope. The voice acting is much worse though, and too grating to deal with
peak ronpa gameplay
第一章案件普通但很感動QQ
its a good danganronpa style game, the story is very interesting and the art and animations are beautiful. I just have a few issues. the card game is important yet lacks any complexity at all- every fight can be won by just max handing then using Erika's skill and wiping an opponent in one turns and more importanly theres just no meat on the bone for this game at all. the only side content is the arcade machine and the claw which are both incredibly simple. the gameplay itself only goes up to the end of chapter 1 and the rest of the chapters will require payment. its definitely worth it but right now its essentially a paid demo with very little content. I cannot emphasise how wonderful the soundtrack and art is though- its frankly beautiful. though some characters designs are...questionable
If I were to give this a numerical rating, it would be a 4/5 or a 9/10. I largely enjoyed this game, but I did have some issues with it. Long-time fans of Danganronpa will enjoy Kumitantei as a fresh take on the series formula. Because Kumitantei takes place in a particular era of Japanese history, it informs the setting and the background of all the characters. It makes for an interesting narrative on the whole, without spoiling anything. As for gameplay, I did enjoy the card-building aspect as well. The various other mini-games are fun for the most part. Now, the reason I wouldn't give this a perfect score is that I did have my own issues. There are some characters I'm not fond of, but I'm not holding it against the game. The character personalities are very diverse, so which ones a person likes depends on the person. Gameplay wise, there was a mini-game I didn't like. Another mini-game entirely lacked a tutorial. But all in all, I say this is a game that is worth a purchase. I am looking forward to future Episodes of this game.
