Murder Mystery 2 review

Murder Mystery 2 had the most people playing of any game on this list when we checked, 458,558, which says a lot for a game first created in 2014. Each round deals out three roles. Innocents run and hide from the Murderer and use detective skills to expose them, the Sheriff is the only one with a weapon who can take the Murderer down, and the Murderer must eliminate everyone without getting shot. Between rounds, players collect and trade hundreds of knives, and the developer posts free knife codes for followers. The Halloween 2026 event adds a retro theme. Rounds are quick and the rules are simple, which makes it a good party game for friends who play different genres. The trade-offs are a Moderate maturity label for light blood and moderate violence, and long stretches of hiding when you draw Innocent. We compared documented features and published prices; we did not play-test it.
