In the social deduction Among Us game Impostors have the ability to kill Crewmates, turning them into ghosts. The kill cooldown ranges from ten seconds to a minute, depending on the game settings. On the first spawn of the match, the Impostor's kill ability cooldown starts at ten seconds from the beginning of the game, but after the first emergency meeting or an Impostor's kill of a crewmate that cooldown gets increased to that specified in the in-game options. But when the time is right and the Impostor makes his move and presses the Kill button a Crewmate hears intense violin music and in case of knives sees an Impostor stabbing him with a knife in his back animation, like in our progress bar here.
