Understanding the Game
MM2 is a round-based survival game where players are secretly assigned one of three roles: Innocent, Sheriff, or Murderer . Each round, you'll spawn on a map, and your goal depends entirely on the role you're given.
Win Conditions by Role
Role | Goal |
Innocent | Survive until the timer ends, or help eliminate the Murderer |
Sheriff | |
Murderer | |
Hero | An innocent who picks up the Sheriff's dropped gun and shoots the Murderer |
Role-Specific Strategies
Playing as the Sheriff
The Sheriff is the only player who spawns with a gun, making you the Innocents' best hope—but also the Murderer's prime target .
Key Tips:
Keep your identity hidden. If the Murderer knows who you are, you'll be their first target .
Wait for clear proof. A wrong shot kills an innocent and leaves your team vulnerable .
Mind the reload delay. The gun needs time between shots. Use it at close to mid-range, not from far away .
Avoid tight crowds. Stay near open areas where you have room to aim .
Don't panic-fire. Take your time to confirm the Murderer's identity before pulling the trigger.
Playing as the Murderer
The knife is given shortly after the round starts, so use the first moments to blend in .
Key Tips:
Pick off isolated players first. Then pressure groups when the Sheriff's position is unclear .
Blend in. Act innocent—don't draw attention to yourself early .
Use the environment. Corners and tight corridors give you an advantage; surprise attacks are harder to dodge there .
Exploit Sheriff mistakes. If the Sheriff misses a shot, that reload window is your chance to strike .
Throw your knife. On PC, hold E or right-click to throw the knife at distant targets .
Playing as an Innocent
As an Innocent, your best weapon is information. Watch player movements, deaths, and who is running from where .
Key Tips:
Stay in groups (but not too close). Stick with others to reduce the chance of being targeted .
Avoid predictable patterns. Don't use the same hiding spot twice. Mix up your routes when collecting coins .
Know the map. Avoid rooms with only one exit and tight corridors where the Murderer can trap you .
If the Sheriff dies, the gun drops. Pick it up to become the Hero, but don't rush blindly—the Murderer may be camping it .
Collect coins when safe. Survival matters more than coins, but coins unlock cosmetics and crates .
Perks That Give You an Edge
Perks can dramatically change how you play. Here are the most powerful ones:
Perk | Effect | Why It's Great |
X-Ray | See through walls for 4 seconds (26s cooldown). See dead bodies, innocents, sheriff, and gun | |
Haste | Move 10% faster with knife out | |
Ghost | Turn invisible for 5 seconds (30s cooldown) |
X-Ray costs 6,000 Coins or 800 Diamonds in the shop—a worthy investment for serious players .
Map Awareness and Positioning
Map knowledge is critical for survival. Different maps offer different advantages .
General Tips
Learn common hallways, hiding spots, and dead ends on each map .
Open spaces are safer for Sheriff and Hero—more room to aim .
Tight corridors help the Murderer—avoid them if you're not the killer .
If you hear chaos nearby, rotate away instead of following the crowd blindly .
Recommended Maps for Mobility

Advanced Tricks & Community Knowledge
Identifying Players Early
Look for these behavioral tells :
Erratic behavior – Chasing without reason usually means Murderer.
Corner-camping – Hiding in isolated spots is suspicious.
Weapon reveals – Sheriffs often reveal their gun early to show trust. Murderers avoid revealing their knife.
Coin avoidance – Players who don't collect coins might be blending in while waiting to attack.
Dealing with Teamers
Teamers (players colluding across roles) can ruin a round :
Stay mobile – Run constantly to avoid being trapped.
Watch for unnatural behavior – If the Murderer walks past someone without killing them, they might be working together.
Report – Teamers can be reported through the game's reporting system.
The "Hero" Play
If the Sheriff dies, the gun drops. Picking it up makes you the Hero. But be careful—the Murderer often camps the gun . Use a distraction or pretend to walk away before returning to grab it .
Trading Guide for MM2
Trading is a major part of MM2, allowing you to exchange knives, guns, and pets with other players .
Requirements
Reach Level 10 to unlock trading (added in December 2021 to prevent scams)
Have tradeable items in your inventory (default items cannot be traded)
How to Trade
Click the player you want to trade with from the player list
Select "Trade" from the menu
Add items to your offer and review theirs
Click "Ready" when satisfied
Once both players confirm, the trade goes through
Important: Each trade is capped at 4 items per side .
Checking Fair Value
MM2 item values are community-agreed, not official. Use value-checking sites like BloxSwaps or Supreme Values to compare offers .
Common results:
Win – You're getting more than you're giving
Fair – Both sides are close in value
Loss – You're giving away more than you're getting back
Avoid Scams
Cross-reference values across multiple sites before high-value trades
Watch for data lag – Some value checkers rely on manual updates
Take your time – Scammers pressure you to accept quickly
