How a round works
Each round starts in the lobby, where players vote for the next map. Then everyone gets a secret role at random:
| Role | Goal | Tools |
|---|---|---|
| Innocent | Survive until the timer ends and help expose the Murderer | None at the start; can pick up the gun |
| Sheriff | Find and shoot the Murderer | A gun, the only weapon on the Innocent side |
| Murderer | Eliminate everyone without getting shot | A knife you can stab or throw with |
If the Murderer runs out of time, the Innocents win. If the Sheriff goes down, the gun drops on the floor and any Innocent can pick it up and become the hero of the round.


Maps and the lobby
Between rounds everyone waits in the lobby. This is where you vote for the next map, check your inventory, open the shop and see your level. Learning the maps is the biggest single upgrade for any MM2 player: once you know where the corridors loop and where the dead ends are, you survive longer as an Innocent, you find the Murderer faster as the Sheriff, and you know where to catch people alone as the Murderer. Vote for maps you know when you are learning, and try new ones once you feel comfortable.
Tips for Innocents
- Know your way out. Plan an escape route as soon as the map loads and avoid dead-end rooms.
- Hide, but do not freeze. Pick a hiding spot near an exit instead of running in circles.
- Keep collecting coins. Coins are your shop money, and moving between coins keeps you away from the crowd.
- Change your path. A thrown knife needs a predictable target. Zigzag and vary your routes.
- Watch for the gun drop. When the Sheriff falls, the gun is your chance to win the round.
Tips for the Sheriff
You get one job and one gun. Pick a spot with a good view of the map, but do not stand still in it all round. Watch for anyone acting strange: running at people, hanging back alone, or following someone into a quiet corner. Shoot only when you are sure. Hitting an Innocent costs you the round, and a wasted moment lets the Murderer close in.

Tips for the Murderer
Act normal at first. Running at the first player you see gives you away to the Sheriff. But do not wait too long either, because the Sheriff is hunting you from the first second and the timer is on the Innocents' side. Catch players alone, use thrown knives when someone is far away, and keep moving so the Sheriff never gets a clear shot.
Coins, the shop and levels
Coins spawn around every map. Pick them up in any role and spend them in the lobby shop on weapons, boosts and emotes. Gems are the premium currency, bought with Robux. You also level up just by playing, and the game hands out badges every ten levels up to level 100.

Mistakes new players make
- Running in circles. Nonstop sprinting puts you in front of the Murderer sooner or later. Move with a plan.
- Hiding in a dead end. A great hiding spot with one exit is a trap.
- Shooting too early as Sheriff. One wrong shot loses the round for your whole team.
- Ignoring coins. Coins buy everything in the shop. Grab them whenever it is safe.
- Murdering in front of everyone. The Sheriff only needs to see you once.
Playing with friends
MM2 is at its best with a group in one server. Rounds are short, roles change every time, and the chaos of a friend turning out to be the Murderer is the whole fun. Servers hold 12 players, so a big group can fill most of a server together. Remember that roles are secret: telling your friends in chat who the Murderer is spoils it for everyone else.
Knives, guns and Godly weapons
The game page sums it up: "Collect and trade hundreds of knives!" Weapons come in rarities, and the rarest tier most players talk about is Godly. A few Godly weapons and bundles are sold as game passes on the official game page; most of the collection comes from boxes, events and trading.


Quick role checklist
Innocent: exits, coins, keep moving. Sheriff: watch, wait, one clean shot. Murderer: blend in, catch players alone, keep out of the Sheriff's sight. Print that in your head and you are already better than half the lobby.
MM2 for younger players
MM2 has a scary name, but the game is cartoonish: rounds are short and nobody loses anything when they are knocked out, they just wait for the next round. The trading side is where younger players need care. Trade only with friends you know, never give your items first, and ask a parent before buying anything with Robux.

Why MM2 is still huge after twelve years
Murder Mystery 2 has 32.2 billion visits and nearly 25 million favorites on Roblox. It never needed a big map or a long grind. Each round takes a few minutes, the three roles are clear to a brand new player, and the weapon collection gives regulars something to chase. Seasonal events bring new skins every year, and the round itself has barely changed, which is exactly why people keep coming back.
Events in November 2026
MM2 is running its 2026 Halloween event in early November. Check the event board in the lobby for what is left and when it ends. If you like quick rounds with friends, try RIVALS next, and for a calmer evening, Brookhaven RP. Everything else is on the Roblox hub.
