Murder Mystery 2 is one of Roblox's long-running social deduction games, where players take on the roles of innocent, sheriff or murderer and try to survive or identify the killer in each round. Because its rounds are short, tense and full of sudden reveals, clips from the game travel well as short-form video, and its sound effects have become a shorthand for that same tension in edits. Creators reuse them to signal danger, betrayal or a surprise ending, even in videos that are not strictly about MM2 itself.
