This Catalog Mystery guide covers what you need to know about Catalog Mystery on Roblox: how to play the three roles, what the three game modes change, and how to redeem the active codes. It was written by Priya Sundaram, GameLand Insider’s Guides & How-To Editor. For game stats and related content, see the Catalog Mystery game hub. The game launched on Roblox on 18 May 2026 and passed five million visits in under three weeks. It has around 6,600 concurrent players and a 92% like rate, strong numbers for a murder-mystery title built around 12-player rounds.

If you have played Murder Mystery 2 (game hub) before, this game feels familiar: one hidden killer, one armed investigator, and a group of unarmed civilians trying to stay alive. What makes it different is the Roblox Catalog layer. The weapons (knives, scythes, and trophies) are themed around catalog items instead of generic skins, and you unlock them through codes or in-game progress. For a similar title with the same 1-vs-all knife format, the Cyrus Infinite guide covers the Cyrus’s MM2 group’s May 2026 launch.

Catalog Mystery Guide: What Is the Game?

Catalog Mystery is a murder mystery survival game in the 1-vs-all format that titles like Murder Mystery 2 and Survive the Killer made popular. Each round hands players one of three roles at random. This Catalog Mystery guide covers all three, because the result depends on how well each side does its job. The game supports up to 12 players per server, big enough to give the Murderer cover but small enough that every choice matters. You cannot pick your role.

Catalog Mystery Guide: Your First Match

This part of the Catalog Mystery guide walks through one full match so you know what to expect.

Joining a server: Open the game and press Play. You join a lobby with up to 11 other players, and the countdown runs about 30 seconds. Fewer players means fewer Innocents, which tips the balance toward the Murderer.

Role assignment: The server gives each player a role at random: one Murderer, one Sheriff, and the rest Innocents. Your role is private, and it changes every round.

During a round: An Innocent has no weapon. The Sheriff spawns with a gun. The Murderer spawns with a cosmetic melee weapon: a knife, scythe, or trophy. The round can end three ways:

  • The Murderer eliminates every other player, and the Murderer wins.
  • The Sheriff, or an Innocent who picks up a dropped gun, shoots the Murderer, and the Innocents win.
  • The timer runs out, and the Innocents survive by default.

Controls: Standard Roblox controls. Move with WASD or the on-screen joystick on mobile. The Sheriff fires with a left click or tap, and the Murderer’s melee weapon works on proximity.

Catalog Mystery Guide to the Three Roles

Your role is the most important part of this Catalog Mystery guide. Roles are random each round, so getting good means playing all three well.

Playing Innocent

Innocents make up most of each lobby, usually eight to ten players. You cannot attack, so your only defense is movement: run, use cover, and stay near the Sheriff without bunching up. If the Murderer takes out the Sheriff, an Innocent who grabs the fallen gun can take the shot. That is the one moment an unarmed player can decide the round. Watch for players who act out of pattern, like those who linger near the edges or drift toward isolated targets.

Playing Sheriff

Each round has one Sheriff, the only Innocent with a weapon. Your gun holds one shot before a reload window, so accuracy matters. A missed shot that hits an Innocent is a round-ending mistake. Be patient: call out odd behaviour in chat and wait for the Murderer to make an aggressive move.

Playing Murderer

The Murderer gets a melee weapon and must eliminate everyone before the timer runs out or the Sheriff shoots them. Good play is about misdirection: stay near groups without targeting anyone, time kills when few people watch, and find the Sheriff early. Once the Sheriff is gone, the round is almost yours.

Catalog Mystery Guide to All Three Game Modes

One of the game’s best additions over plain Murder Mystery 2 clones is its three modes, and no Catalog Mystery guide is complete without all of them. They share the same roles but change the rules.

Standard Mode

The baseline. Roles are handed out, the Murderer hunts, the Sheriff investigates, and the Innocents survive until the round ends. If you are new, start here.

Disguises Mode

The Murderer can take on the look of another player’s character for a while. That adds real doubt, because the player running toward you might be a teammate or the Murderer in disguise. Trust behaviour over looks, and track anyone who changes direction right after a disguise switch.

Assassin Mode

Each player gets a secret target instead of one Murderer against all. It plays like a social deduction game where everyone is both hunter and hunted. There is no Sheriff and no safe Innocent, since every player has a weapon. It runs at the highest intensity of the three, so it suits experienced players best.

Catalog Mystery Guide Tips for Every Role

These Catalog Mystery guide tips apply across all three modes unless noted.

Innocent Tips

A crowd of five slows reaction time and gives the Murderer a dense target. Two or three is the sweet spot. Track who has been in view for the last thirty seconds. The player who moves with confidence is usually the Sheriff. Stay in view of them without crowding. Pick up a dropped gun only if it is safe. Do not stand still: keep moving and avoid corners.

Sheriff Tips

Hold your shot. Hitting an Innocent by mistake is worse than waiting for a clear read. In Disguises Mode, never shoot on a look change alone. The Murder Mystery 2 tier list has breakdowns that map onto the Sheriff role here. Do not announce yourself. Move like a normal Innocent until you have a high-confidence shot. Do not fire at a player you are less than 80% sure about. In Standard Mode, patrol instead of hiding. Sheriffs who sit in corners get found first.

Murderer Tips

Your biggest tell is impatience. The Murderer who waits usually outlasts the one who strikes first. Find the Sheriff early, since they are your only real threat. Kill when the target is alone, because kills with witnesses point the Sheriff right at you. In Assassin Mode, avoiding all contact is wrong. Every player has a weapon, and moving too carefully reads as inexperience.

Common New-Player Mistakes

New players make the same three errors, one per role, and they are the ones this Catalog Mystery guide flags most. As an Innocent, chasing the Murderer without a weapon just makes you next. Run away and alert the Sheriff in chat. As the Sheriff, firing at the first suspicious move backfires, because suspicion is not proof. As the Murderer, attacking players near groups gets you spotted. Go after isolated players instead.

Catalog Mystery Guide FAQ

Quick answers to the questions this Catalog Mystery guide gets asked most:

What is the game?

Catalog Mystery is a murder-mystery survival game for up to 12 players. Each round assigns one of three roles, and it ends when the Murderer eliminates everyone or the Sheriff shoots the Murderer. The name comes from the Roblox Catalog cosmetic system, used for weapon skins you redeem with codes.

How do you redeem codes?

Open the Inventory icon in the HUD, find the text box at the bottom of the panel, type the code exactly (it is case-sensitive), and press Redeem. The active codes at this Catalog Mystery guide’s June 2026 check are N3WC0D3, R4YGUN, and S2NBL4D3.

What are the three game modes?

Standard Mode is the basic format. Disguises Mode lets the Murderer look like another player for a short time. Assassin Mode gives every player a secret target instead of one Murderer.

How many players are supported?

Each server supports up to 12 players, with role assignment randomised every round.

Is it the same as Murder Mystery 2?

No. Catalog Mystery is a separate game by a different developer (KMM reupload) with a similar role format. It is not a sequel to Murder Mystery 2. The differences are the Catalog cosmetic system, the three game modes, and the newer way codes are shared through Roblox developer profiles.

Where do new codes get posted?

Codes are announced on two Roblox profiles listed in the game description: @27th07s and @ch4rmforever.

What happens when the Sheriff dies?

The Sheriff’s gun drops where they died. Any Innocent can pick it up and shoot the Murderer. If no one grabs it, the remaining Innocents must survive until the timer runs out.

Is it good for beginners?

Yes. The role system is simple, and new players can help as an Innocent right away. The Sheriff and Murderer roles ask more, but they are random, so beginners get time to watch first.

How many visits does the game have?

As of 3 June 2026, the game has over five million visits, about 6,600 concurrent players, and a 92% like rate. It launched on 18 May 2026 and reached these numbers in under three weeks.
