Murder Mystery 2 is a Roblox horror game created by Nikilis. The game is based off a Garry’s Mod game mode called Murder. A server holds up to twelve players, with one «murderer», one «sheriff», and ten «innocents» at most. The game features three modes: Casual, Hardcore, and Assassin. These modes can be switched at any time by the user.
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 XP for killing the murderer. It will increase the XP depending on how many innocents they successfully protect.
The innocents are unarmed and cannot harm the other players. Their goal 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 XP depending with the activity of the player such as the time survival and making their coin bag full, and the hero gets the same XP as the innocents with a increase of winning the round, 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 the time runs out.
