The game consists of three very challenging levels. In each level, you will have a few people to kill. But the condition is- you can’t kill anyone with others being alarmed. That means, you are not allowed to have any witness. There are strategies in this game which you need to follow to pass the levels. Timing is very crucial here. Sometimes, you may see no way to kill one or two persons. Don’t worry; you can search for a walk-through for the game. But I would suggest you to try something on your own. Try to find the correct order to kill the people.
