About This Game

One mansion. One evening. One murderer among the guests.

Murdeo is a first-person social deduction game for 4 to 12 players. Everyone arrives as a guest or as staff of a country mansion – host, cook, maid, gardener, janitor. One of you is secretly the murderer. One of you is the detective. Everyone else just wants to survive the night.

Blend in or be found out

• Every role has its own duties around the house: cooking, cleaning, tending the garden, preparing dinner. Doing them keeps you above suspicion.

• The murderer has a cover profession too, and has to play it convincingly while hunting for the right moment.

• A knife is silent. Choose your moment, find a quiet corner, and don’t get seen.

The mansion keeps its secrets

• Explore a large mansion with dozens of rooms, a grand hall, a dining room, a library and grounds outside.

• Hidden doors and secret passages let you disappear – or surprise someone.

A security hut with cameras watches the house – unless the power goes out.

Murderer vs. Detective

• The detective carries a revolver with a single round. One shot – make it count.

• Examine bodies to earn points, then use them on tools like a trail that leads to the killer.

• The murderer earns points too: take on another guest’s appearance, or sense victims through walls.

Talk, accuse, survive

• Proximity voice chat: you hear the players near you, muffled through walls and doors.

• The dead can still talk – but only to each other. The living never hear them.

• Join a running round as a spectator and follow the evening until the next one starts.

AI disclosure: No AI-generated art, models, music or sounds are used in Murdeo. All visual and audio assets are hand-made or licensed asset packs. Parts of the game's code were written with the help of AI tools.

AI Generated Content Disclosure

The developers describe how their game uses AI Generated Content like this:

AI tools were used to write and translate the game's texts (interface and localization in all languages) and the store page text. All 3D models, textures, animations, music and sound effects are made by people or come from licensed asset packs.

Mature Content Description

The developers describe the content like this:

Murdeo contains violence in a stylized, low-poly art style. One player secretly plays a murderer who kills other characters with a knife; the detective can shoot suspects with a revolver. Killings show brief blood effects, blood stains and bodies lying in the mansion. There is no sexual content, no gore beyond this, and no depiction of drug use or self-harm.
