It is difficult to say how humane such a method of dealing with imposters as a quick kill is. But the crew members consider it as efficient and effective as possible. However, it is quite difficult to defeat them when they have weapons in their hands, and in numbers they have an advantage. Therefore, the killer of imposters will have to work hard to succeed. Sneak like a mouse, run up from behind and stay out of sight of enemies. Then you will be able to save your health and complete a rather difficult mission. Good luck in the game!
