The Spy's silent K.O.
weapon comes in handy when you need to drug the enemy and borrow somethnig from or use him.
Don't forget to tie up the enemy after, you don't want him to wake up and raise an alarm.
TIP: trying to put to sleep the enemies when they are aware of your presence
(for example in the eyes) will bring no effect whatsoever.
