Summary
Murder Mystery 2 (MM2) is a wildly popular Roblox game where players are assigned one of three core roles: Innocent, Sheriff, or Murderer—but when custom rules and special roles like the Traitor or Admin enter the mix, the game becomes a whole new experience. This guide covers the wildest custom roles you can encounter and how to master them, and if you want to stand out with rare knives or effects, you can always buy MM2 Items to customize your loadout.
The Core Roles (Standard MM2)
Before diving into custom roles, here's the standard setup:
Role | Goal |
Murderer | Kill everyone without being shot by the Sheriff |
Sheriff | Find and shoot the Murderer |
Innocent | Survive and help identify the Murderer |
Hero | An Innocent who picks up the Sheriff's dropped gun |
Custom Roles You Can Encounter
In modded servers or custom rule games, you can get assigned some truly wild roles. Here are the most notable ones:
1. Traitor
The Traitor works alongside the Murderer as a teammate. Both share the same goal: eliminate the lobby.
Key Mechanics:
The Traitor can see the Murderer's location
The Murderer cannot see the Traitor
The Traitor cannot kill the Murderer (they're teammates)
If one dies, the other can continue
Traitor Tactics:
Coordinate with the Murderer—you're on the same side
Don't accidentally kill your partner
The Sheriff can still take you out, so stay alert
Use your knife to eliminate Innocents while the Murderer creates chaos
2. Admin (The Command Role)
If you get the Admin role, you unlock special commands that let you control the game. You don't just play—you become the puppet master.
Admin Commands Include:
Command | Effect |
Morph | Copy another player's appearance |
Big Head | Make someone's head huge |
Shrink | Reduce a player's model size |
Ghost | Become invisible and phase through walls |
Disco | Turn on disco lights and dance |
Dino | Transform into a dinosaur |
Aura | Emit a glowing aura |
How to Get Admin Commands:
By default, you can't use these. You need permission from the developers—join the MM2 Discord, ping a Community Member, explain your use case (content creation, tournaments), and they may grant you access for private servers.
Admin Tips:
Morph into other players to confuse everyone
Use Ghost to avoid detection while hunting
Combine commands for maximum trolling potential
3. Hacker (ESP/Wallhacks)
The Hacker role gives you wallhack abilities—you can see every player through walls.
Key Mechanics:
Full ESP (Extra Sensory Perception) view
See exact player locations at all times
As the Murderer with this role, you're virtually unstoppable
Hacker Tips:
Use the wallhack to locate isolated players first
Don't reveal your ability too early—surprise is your advantage
Watch for the Sheriff's position before striking
Pick off players one by one from the edges
4. Owner (Full God Powers)
The Owner role gives you god-tier abilities. You're basically the game master.
Owner Abilities:
Ability | Effect |
Fly | Fly anywhere on the map |
Freeze | Freeze other players in place |
Kill | Instantly eliminate anyone |
Fling | Launch players across the map |
Explode | Make players explode |
God | Become invincible |
Owner Power Moves:
Fly above the map to avoid detection
Freeze the Sheriff before they can shoot
Morph into other players to confuse everyone
You're nearly invincible—even gunshots may not kill you
5. Survivor & Infected (Zombie Mode)
This is an event mode where the game turns into infection-style gameplay.
How It Works:
Survivors start with guns and try to avoid infection
The first zombie is an NPC; infected players become zombies
Zombies infect survivors by touching them
If you get infected, you lose your gun and gain a knife—you switch sides mid-round!
Survival Tips:
Stick with other survivors—there's safety in numbers
Watch for the initial zombie NPC
Once infected, embrace your new role and spread the infection
Keep moving—stationary survivors are easy targets
6. 99 Knights (Chaos Mode)
A chaotic role where you're transformed into a small "dino kid" and must eliminate everyone using random weapons you receive.
Key Mechanics:
Your avatar shrinks and changes
You receive a ton of random guns (including AK-47s!)
Everyone is hostile—it's a free-for-all
Strategy:
Use the element of surprise—no one expects the tiny dinosaur
Spray and pray—with that many guns, accuracy isn't your main concern
Keep moving to avoid getting shot
How to Identify Roles
In custom games, it's not always obvious who's who. Here are some tells:
Role | Tell |
Murderer | Holds a knife; may have a "clink" sound |
Traitor | Can see the Murderer; may reveal themselves by not attacking |
Admin/Owner | Uses morph commands; flies; freezes players |
Hacker | Knows exactly where everyone is hiding |
Survivor | Starts with a gun and wants to stay away from zombies |
Infected | Red/green tint; moves differently; has a knife |
Map Awareness Tips
Knowing the map is crucial regardless of your role:
Innocents: Stay in open areas with multiple exits. Avoid dead-end rooms where the Murderer can corner you.
Sheriff: Take elevated positions or doorway angles for maximum sightlines.
Murderer: Funnel targets into enclosed spaces where the Sheriff can't take a clean shot.
Traitor: Stay near the Murderer but not too close—you want to support without drawing attention.
General Strategy by Role
As Murderer
Blend in by mimicking Innocent behavior—walk casually, collect coins
Don't rush kills; methodical, sneaky kills keep you hidden longer
Use the map to trap people and escape quickly after kills
With a Traitor teammate, create chaos—split up to cover more ground
As Sheriff
Stay mobile—stationary players are easy targets
Watch for players who isolate themselves or chase others suspiciously
Don't reveal yourself too early
If you suspect a Traitor, watch for players who avoid attacking the Murderer
As Innocent
Observe player behavior and chat to identify the Murderer
Know the map's escape routes to avoid being cornered
If the Sheriff dies, decide carefully whether to pick up the gun
Watch for players who seem to be protecting someone—that might be the Traitor
As Traitor
Coordinate with the Murderer—you're teammates
Use your ability to see the Murderer's location to set up ambushes
Don't kill the Murderer (obviously)
The Sheriff doesn't know who you are—use that to your advantage
As Admin/Owner
Have fun—you're the game master
Use commands strategically, not just for chaos
Morphing into other players is your best tool for deception
Freeze threats before they can act
Final Thoughts
Murder Mystery 2's custom roles add a chaotic and hilarious layer to the classic formula. Whether you're Admin with full god powers, Hacker with wallhacks, Traitor working alongside the Murderer, or a Survivor fighting off zombies, each role brings a completely different experience. To make the most of these wild game modes, you can find MM2 Items for sale at trusted platforms like MMOEXP, so you can grab rare knives, guns, and effects to match your favorite role.
The key takeaway? Adapt to your role and use your abilities strategically. The custom roles are powerful—but only if you know how to use them. Morph, fly, hack, and infect your way to victory!
