Free-For-All is the successor of Murderer Madness gamemode that occurred on random interval in the Mad Murderer. All players receive a knife after a short intermission. The murderers then must fight each other, last player alive wins. It doesn't matter how many players you kill, the game will award your prize depending how many players were eliminated before you. Hiding until the hassle has set a bit before charging into other players can be an effective tactic, but many players consider it a cheap way to win.
