About this game
Description
Supplied by the Steam store
Murders & Mistresses is a dark, choice-driven adult detective thriller about sex, power, judgment — and consequences.
You play a brilliant ex-conman turned police consultant — cocky, charismatic, dangerously persuasive — surrounded by women you shouldn't be sleeping with, and given far too much freedom.
A character-driven prestige drama: the story will force you into uncomfortable places, and your choices will have severe consequences.
What You're Getting
5 cases — three murder investigations, a hostage negotiation, and a kidnapping
40+ sex scenes with 145+ animations
3 marriage paths — Exclusive, Open, and Semi-Open (she shares you, you don't share her)
Dates, hangouts, and hookups across the city — seduce suspects, fool lie detectors, play tabletop RPGs, negotiate threesomes, or go on self-destructive benders
A branching flowchart for every chapter — see everything you missed and replay any chapter, anytime
Two ways to solve murders — Story Mode or Detective Mode
A complete game, start to finish — not just an episode
Investigate Murders and Outsmart Killers
From a brutal double homicide to an impossible locked-room mystery to a hostage negotiation where one wrong word gets someone killed — every case demands a different kind of thinking.
A Detective Game about Judgment — Not Proof
Facts only get you so far: you read people, form a theory, and name who you believe is guilty — often without proof.
There's no solution screen, but the truth exists — every case has a real culprit and a real motive, whether you find them or not.
Two Ways to Solve a Murder
Story Mode — Investigate, deduce, interrogate — then choose who you believe is guilty and why.
Detective Mode — Same cases, same evidence, deeper reasoning: combine deductions into case theories, and theories into bigger ones, until yours explains the whole crime. 6,000+ combinations. 550+ case theories. One truth.
Innocent Until You Say Otherwise
Arrest who you want — the game won't stop you, but it'll remember.
Your choices decide who loves you, who hates you, who goes to prison, and who dies. Guilty or innocent — no one is safe.
See Everything You Missed
After every chapter, your flowchart opens — every scene you played, every important choice, and every scene you didn't see.
Replay any chapter from there or from the main menu, skip what you've seen, and find out what would have happened if you'd chosen differently.
Life Outside the Case
Celebrate closing a case with your colleagues, flirt with your boss, or go on ethically questionable dates with ex-murder suspects — which lines you cross is up to you.
Shape Your Marriage — and Your Sex Life
Explore a kinky and loving marriage with your gorgeous wife. Which marriage you choose — and whether you respect it — is yours to decide.
Exclusive — she's yours alone, expects the same, and rewards it. Cheat on her at your own risk.
Semi-Open — she shares you; you don't share her. She may ask to watch, or to join.
Open — all of Semi-Open, and you share her too. You may watch, or join.
She's all in on whichever marriage you choose — no resentment, no secrets, no humiliation.

Murders & Mistresses v1.0.0.3 Patch notes
Hey everyone! We hope you've been enjoying Murders & Mistresses! If you wanna support us, leaving an honest Steam review would be a huge help for our visibility! Thank you! Now let's get to the patch notes. This is the first patch since Steam release and our goal was to improve quality of life with some much requested features (like turning off autosaves), fix any bugs players had come across, and also fix small visual problems in a number of images and animations.You can find a full list of changes below:NewNew autosave setting in Options: On every Choice (the default), Every 15 Minutes, or Off. If picking choices has been causing hitches or freezes for you, try lowering the autosave amount.Autosaves are now off in Real Life Mode.In cases 1–3, pressing I now only highlights things you haven't looked at already, not everything. Doors and exits always light up.Chapter title cards for c...
Read full update on Steam ↗Murders & Mistresses July Dev Update: 1,000 Combinations Later…
Hey everyone, It's nearing the end of July, and M&M is looking really freaking good! We're currently finishing up the release date announcement trailer. The first trailer was information-focused — it walks you through the gameplay and core mechanics — so this second one is the opposite: faster, punchier, and built purely to get you excited about what's coming. We'll be releasing it in the next few weeks alongside the announcement of exactly when M&M will release, so stay tuned for that!Other than that, it's been a busy month development-wise.I talked in last month's update about what my version of playtesting involves — it's like directing, editing, and bug-fixing a scene all in one — and I'm now about halfway through the entire game. It's genuinely exciting, not just because I finally get to play the game we've spent the last 18 months making, but because I get to make it even better...
Read full update on Steam ↗Murders & Mistresses June Dev Update: The game is taking shape!
Edit: Had some technical issues publishing this but here's the progress update for June for those who haven't seen it already, July to follow this evening! Hey everyone,It's near the end of June, and Murders & Mistresses is starting to look incredible. Earlier this month I officially started playtesting the game, and with nearly two-thirds of all the renders and animations now finished, there's a lot of game to actually play through. When I first drafted M&M back in early 2025, I wrote it directly in code. But there's a huge amount of work between that early version and the polished full game you guys will be playing soon.Outside of creating the artwork, coding the mechanics, building the UI, and sourcing the music — all of which we've been doing throughout production — my job now is mainly to put it all together and make sure every line, every image, and every transition is exactly w...
Read full update on Steam ↗Murders & Mistresses May Dev Update: The Long Road to Release
Hey everyone,May has been another steady production month for Murders & Mistresses.At this stage of development, a lot of the work is less about announcing brand-new features and more about pushing the game closer to completion scene by scene, image by image, and track by track. That can be a bit of a slog, but it also means we’re genuinely moving toward the finish line.This month, we continued the render grind and completed more artwork across several parts of the game, including the vacation storyline, the second case, and late-game map content. We don’t always produce the game in chronological order, so some of the scenes being worked on now are from sections much closer to the end of the game, which makes them even harder to talk about without spoiling anything! We’ve also been doing a new music pass across the game, adding and adjusting tracks to better support the atmosphere of...
Read full update on Steam ↗Murders & Mistresses April Dev Update: Life Outside the Cases
Hey everyone,April has been a strong month for Murders & Mistresses, and development continues to move forward well as we work toward our summer release.A lot of this month’s production has focused on the parts of the game that unfold between the major detective cases. The murders and investigations may drive the story, but the world around them matters just as much: a birthday party where everyone is dressed for trouble, a wild vacation with your insatiable wife, and plenty of tempting distractions around the city to pull you away from the grisly realities of your job.We’re keeping many of our favorite moments under wraps for now to avoid spoiling too much, but we wanted to share a few glimpses of what we’ve been building this month.Thank you all for your continued support! We plan on releasing a new dev update with teaser images every month from now until release.-Steve
