Players were disguised by receiving a different name, which was based off the NATO Phonetic Alphabet and their avatars were also altered to appear similar.
Once a map was chosen, players would be teleported to the chosen map and given the roles of either Murderer, Innocent, or Sheriff, along with a costume disguise. The Murderer's objective was to kill all players and avoid being shot by the Sheriff, while the Sheriff's objective was to discover who the Murderer was and to shoot the Murderer, Innocents had to survive and witness murders. Although, if the Sheriff died, their gun could be picked up by an Innocent to shoot the Murderer.
Murderers had the unique ability to see other player's footsteps, along with acquiring unique abilities based on the knife they had bought and equipped.
Murder Mystery was a popular game for its time, it had inspired the creation for other murder mystery-themed games on Roblox. Murder Mystery's maps have also been recreated as playable maps in Murder Mystery 2.
Notes & Trivia
- Knives that were bought before the update to Murder Mystery 2 appeared in player's inventories with a tier of their own, Classic, which was later renamed as Vintage.
- Players used to be able to grab the knife from the Murderer's hand, this was most likely unintentional.
