The premise of the game is pretty simple. You have to sneak up on other players and then take them out. In this case, though, the crewmembers are not other players; they are simply controlled by the computer, and normally, they don’t move.
The obvious solution is to take out the ones that are looking at you first. The ones that are not looking at you will either not notice what you are doing, or they will turn around and be scared. If you do it the wrong way, then the wrong crewmember might notice you and arrest you.
