Platforms and cross-play
- Platform: Roblox — one install covers PC, mobile, console and tablet
- Cross-play: on by default, matching how Roblox experiences work; you can queue with friends on different devices
- Price: the Roblox experience itself has not been announced as paid; the standard expectation for Roblox games is free entry with optional purchases, but the developer has not confirmed monetization details (marked 待确认)
How to play Monsters in the Mansion
- Open the Roblox app (or roblox.com in a browser) and search "Monster in the Mansion" / "Monsters in the Mansion".
- Enter through the official site if you prefer a link — the studio's game page at art-af.studio carries the official play entry, Discord, YouTube and X links in one place.
- Join a round. Eight players enter Doctor Mondo's mansion; one is possessed by the Monster.
- Play your side. As the Monster: hunt by sound and sight and deny the cure (How to Play the Monster). As a Survivor: collect hidden books, brew the antidote, cure the Monster (How to Cure the Monster).
- Set push-to-talk before your first round. Voice chat is audible in-game — this one setting changes your survival rate more than anything else (How to Survive).
Before your first round: the 60-second primer
- Rounds are 8 players: 1 Monster vs 7 Survivors — there is no exit, the win condition is the cure
- Roles are assigned at spawn: runners, decoy, cure carrier, support (Beginner Guide)
- The Monster hunts by sound first, sight second — crouch-walk, flashlight off
- Codes exist yet? Not confirmed — check the codes snapshot and ignore the fake FULLRELEASE posts
