Murder Mystery 2

Overview

Murder Mystery 2 (MM2) is a survival and deduction game on Roblox created by Nikilis. Each round, players are assigned one of three roles: Innocent, Sheriff, or Murderer. Innocents must survive and use detective skills to identify the killer, the Sheriff is the only player armed to take down the Murderer, and the Murderer's goal is to eliminate everyone without getting caught.

Classified under the Survival genre with a "1 vs All" subgenre, MM2 has been live on Roblox for over 4,448 days — roughly 12 years — making it one of the platform's longest-running hits. Beyond the core gameplay, MM2 is widely known for its deep trading economy centered around collectible knives, including coveted "godly" and "ancient" tier items. Regular seasonal events tied to holidays like Halloween and Christmas introduce limited-time maps, game modes, and exclusive weapons that keep the community engaged year after year.

Player Count & Trends

Murder Mystery 2 currently has approximately 174,210 concurrent players online. Over the past 24 hours, the game's player count has surged by 33,271 players, representing a 27.3% increase — a strong upward trend that signals renewed interest or a recent event driving engagement.

The game maintains a peak ratio of 0.70, meaning its current player count sits at roughly 70% of its recent peak. This indicates MM2 is performing near its ceiling and sustaining high engagement rather than experiencing a temporary spike. With a retention ratio of 0.0097, the game continuously draws from an enormous funnel of total visits to maintain its massive concurrent player base.

Revenue & Monetization

Murder Mystery 2 generates an estimated $1,059,877 in monthly revenue, placing it firmly among Roblox's top-earning experiences. This estimate carries a confidence level of 0.58, reflecting moderate certainty — actual earnings could be higher or lower depending on seasonal item sales and event-driven spending.

MM2's monetization revolves around in-game purchases such as crate unboxing for knives and cosmetic items, a radio pass that lets players play music during rounds, and pet companions. The game's thriving trading economy, supported by dedicated trading servers and third-party value lists, also drives ongoing engagement with premium items, encouraging players to invest in rare collectibles.

Growth Story

With over 24.5 billion total visits, Murder Mystery 2 ranks among the most visited experiences in Roblox history. The game has amassed 21.4 million favorites and over 9.3 million likes against just 948,439 dislikes, resulting in a strong like ratio of 90.8%. These numbers reflect a game that has not only attracted an enormous audience but has consistently satisfied it over more than a decade.

Notably, Nikilis has built this success with a single published game — MM2 is the sole title under the creator's profile, yet it competes with studios that operate entire portfolios. The game's longevity is fueled by its active YouTube content creator community, regular updates with new maps and knife collections, and a trading culture that has become nearly as central to the experience as the gameplay itself.

How Murder Mystery 2 Compares

Murder Mystery 2 sits in the 100th percentile of its genre, meaning it outperforms every other game in the Survival category on Roblox. It holds a Tier 1 classification — the highest tier — reserved for the platform's most popular and financially successful experiences.

This top-tier ranking is no small feat in a genre filled with competitive titles. MM2's combination of a 12-year track record, 174K+ concurrent players, billion-scale visits, and seven-figure monthly revenue makes it the definitive benchmark for survival and social deduction games on Roblox.
