Murder Mystery 2 is a popular horror game made by Nikilis on January 18, 2014. It is the first game on Roblox to reach 10 million visits. The game is based off a Gmod gamemode named "Murder".

The game features 3 modes: Casual, Hardcore, and Assassin. These modes can be changed at any time.

On December 25, 2014, the game was changed to Version 2.0. The game was broken from May 8, 2015 - August 18, 2015. As of May 8, 2017, Murder Mystery 2 is the most visited and favorited game. However, other front page games such as Jailbreak and MeepCity have long since overtaken MM2 in visits.


A server holds up to 12 players, with 1 murderer, 1 sheriff, and 10 innocent at-most.

The sheriff is the only player that spawns with a gun, which they can use to protect the innocents. If the sheriff is killed (either by shooting an innocent or getting killed by the murderer), the gun will drop, allowing any innocent to pick it up. Sheriffs gain 500XP for killing the murderer and 100XP for each innocent they successfully protect.

The innocents are unarmed and cannot harm the other players. Their purpose is to aid the sheriff by witnessing murders to figure out who the murderer is. If the gun is dropped by a killed sheriff, an innocent can pick it up, becoming the "hero" if they succeed in shooting the murderer. Innocents gain 10XP for each second they survive, and the hero gets 1000XP for killing the murderer, multiplying after each hero.

The murderer is the only player with a knife, which can be used to kill the innocents and the sheriff. They must stealthily kill all the innocents and the sheriff before time runs out. The murderer gets 1000XP for killing all other players.


Weapons play an integral role for both murderers and sheriffs. Murderers wield throwable knives, whereas sheriffs are equipped with a gun. Both roles are able to buy different weapon designs (also called "skins") in the shop, or they can craft their own designs.

All players carry both a knife and a gun, but only the sheriff and the murderer can equip them.

The weapons can be decorated with special effects and death abilities, but they are merely aesthetic and do not affect gameplay.


Maps that have been in Murder Mystery 2, which players can vote for during intermissions.

Map Description
Office This map is a small office map, due to the size, many players vote for it. The reasoning is because players stay in the main room, where it is most populated and the murderer will easily be caught if she/he attempts to kill anyone in the room.This map has since been discontinued.
Officev2 This map resembles much like the first version of the Office in terms of the layout and area. However, many things have changed. For instance, there are no windows on this map, the glass door at the lobby is replaced by two elevators and the typewriters in the main Office have been replaced with more modern computers. Nevertheless, it's still a popular map.
Officev3 This map is similar to the second version though this map has golden walls instead of grey walls and this map is slightly expanded. A popular hiding feature in this map is "Zyleak's hole," a small hole underneath the map.
Italy Italy resembles a small ancient Western town. There used to be a glitch where people can stack and stand in an invisible brick above the roof at the gathering point. This is a bug that has existed since he added the invisible walls on the roofs of Italy (also introduced at the shops leading to the back alley). It has since been fixed. This map has since been discontinued in 2016.
Terraria Terraria is a medieval like course, with two castles and a lake in between. In both castles there is a sky house and if you jump off the sky house at a certain place, you will exploit a glitch that lets you land on a tree. This is commonly used however and isn't really a hiding spot. This map has since been discontinued in 2015.
Haunted House This map is an exact copy of Shedletsky's Haunted House. This map is very big with many dark areas and many hidden corners. Because of its large size, most of the time the murderer are unable to win on this map. Possibly due to its large size and given about the complaints of this map, this map was removed. This map has since been discontinued in 2015.
The Lab A controversial map in Murder Mystery 2, only if playing as murderer, as it has many doors, rooms, and 4 teleporters. It has a scanner that identifies if she/he is the murderer or not. This map has since been discontinued in 2014.
Labv2 This map is somewhat similar to The Lab in terms of the layout, but this map has been changed drastically. For instance, there is a computer lab and two storage rooms combined with a room with a fake ceiling that allows players to hide on top of the lamps. However, due to its large size, murderers usually will strike early in this map. This map has since been discontinued in 2015..
Abandoned Mine The cave-themed map in Murder Mystery. It is a small-sized map. Most areas in this map are very dark. There are many hiding places in the map and there is an Easter Egg where you can see the map builder outside. This map has since been discontinued.
Hotel It is a small-sized map consisting of 5 rooms, a Hotel Reception area and 2 bathrooms resembling the Toilets from the Office Map. The corridors along the stairs are not lit. The murderer usually strikes in the corridor facing the entrance of the bathrooms or one of the hotel room. This map has sometimes been called a "Budget Hotel" by players as there are not many facilities in this map, as one drawback is only 2 of the rooms have bathrooms. This map has since been discontinued in 2016.
Ship It is obvious from this name that the game is played on board a Cargo Ship. It is a small cargo ship consisting of an upper deck with loads of crates and a lower deck with some crates and a bedroom for the crew to sleep in. This map somehow floats in mid-air and was the only map that cannot protect you from falling off the map up until Version 0.6.0a. You can still fall off the stern (back) of the ship. This has since been fixed. This map has since been discontinued because of the easy way to glitch out.
Hospital This map takes place in a rather small Hospital. It consists of several medical wards, an operating room, a help desk, a waiting area and 2 bathrooms resembling the Toilets from the Office and Hotel Maps. There is an Easter Egg whereby in the operating room, Loleris can be seen lying dead on the operating table.This map has since been discontinued in 2017. However this map is brought back to the game.
Hospitalv2 A new version of the hospital map.
House As the name suggests, the map resembles a typical cottage in the Western countries. There is even a basement whereby players can access through an air vent near a bedroom. Due to its darkness, murderers most likely will strike there first in this map and that's why the map is discontinued. This map has since been discontinued.
Housev2 This map is small but popular. This map has many hiding spots, including one behind a TV.
Mansion A small map that consists of 2 bathrooms, a lounge, a possible closet, a dumpster, a small computer lab, and a dining room. The mansion seems to be owned by either Nikilis or Loleris. It's possible to hide behind the dumpster, on top of the ceiling lights in the lounge, and behind some doors. This map has since been discontinued in 2017.
Mansionv2 A remake of the old Mansion map that has many hallways.
Mil-Base A large map with a singular vent and a hidden spot. There is one hallway that leads to a dark room with a red flashing light, a room with controls, another with about eight places to hide, and then a small room with a large window that only consists of controls and a chair. There is also a large area inside that many players converge at and then after that there is a part upstairs with a large circular table and a few boxes, this room is bad for murderers because there is windows on one side of the room showing outside, where many players group up at.
Workplace A medium-sized map that seems to be a call center, according to the background noise. The map has lots of dead ends, so it is recommended to know where you're going if you're being chased by the murderer. There are a lot of hallways connecting to a single room, so it can be possible to grab the gun behind the murderer or if he/she is distracted.
Pond A small map that consists of the pond itself and a few trees scattered around. The trees make very dark shadows, useful for hiding. This map can only be played on the bonus rounds Massacre and Juggernaut. This map has since been discontinued.
Barn A medium-sized map that has the barn, a house, some hay, and gas tubes. The map lacks of cover, so you will have to improvise. The gas tubes can be used to confuse anyone going after you, as the space between them are small. The house can be used for temporary cover. The barn is the main standoff point. This map can only be played on the bonus rounds Wild West and Infected. This map has since been discontinued.
Hotelv2 This map is pretty popular and it is completely lit up unlike the first and there is also a theater added. There is also a hiding spot under the stairs behind some boxes. There is a glitch where players can spawn on top of the map, where they often tease the murderer by standing on the glass where the murderer can see them, but not get them.
Bio Lab It is a very large map, so this makes it a good map for innocents because they can escape the Murderer easily. Mostly, the fight is drawn to the room with a large pillar and some crates.
Police Station It is quite a large map with many hiding spots. The map consists of several rooms including the main entrance/main room, restrooms, a garage downstairs, two offices in the second floor, an interragation room and a jail with two prison cells. There are many vents in the map, leading to many of the rooms and hallways around the map. This makes it easy to get away from the murderer.
Bank The main feature is a metal detector connecting the main rooms with the air vents. The doorway to the bathroom is left open. If anyone that has a concealed weapon walks through these detectors, a loud beeping sound will commence and the lights will flash red. Anyone nearby that can see this will be notified. Only a Sheriff or Murderer can trigger these. A vent near a detector can be avoided if you stick to the wall and slide across. Behind the door, a vault is located. Only someone with a gun can open the vault doors, leading to the other side. This map has the highest coin spawn rate.
Factory There are many hiding places in the map, like on top and inside of the two trucks. But these spots could be easily accessed by the murderer, so be careful and watch out. The truck outside can be hard to get on top of. The most used method is to open the truck, then jump from the inside of the truck, up on the door.


  • If a user is the murderer, deceiving the sheriff is a key goal to not being killed. Following the sheriff tends to increase suspicion! When trying to kill the sheriff, following him from behind increases the chances of not being seen.
  • The Office, Ship or Hotel tend to be easier maps for the murderer.
  • Revealing a gun may increase a user's chances of being killed by the murderer.
  • There is a small chance that a user will be sheriff or murderer two or more times in a row. Because of this, many players may assume that once someone is the murderer, they will be innocent or sheriff the next round.
  • Think carefully about every move. Some murderers can predict where a player will go and end up throwing a knife in that direction!
  • When you are being chased by the murderer, think of where he/she will go.
  • Try to move into different areas and rooms in the map to confuse the murderer, so you can get more time to hide/run.
  • If you have a Boombox it is unwise to use to it during rounds especially as innocent because people more specifically the murderer can track where you are in the map increasing your chances of getting murdered. 
  • When you hear an effect sound check what people have it to know who's murderer
  • The only way to detect a murderer who has turned invisible is through the gun when the target turns red and you see no one is present. The sheriff can only shoot the murderer if he/she is partially visible or totally visible.
  • If you are innocent or sheriff think of who hasn’t been the murderer in a while, it might be them!
