  • Hints
      High jump

      If you are in certain levels (Quarantine Village, Laborers), you do not need a grappling hook to get on to the roof of a house. Run up to the wall, face it, and jump. Your character will jump twice the normal height of the usual jump and land on top of the roof without hanging on the side.

      Easy kills

      Hit an enemy who is not aware of your presence in the head with a blow gun dart to automatically kill them.

      Automatic stealth kill

      You do not need to pull out your weapons to perform a stealth kill. Run to the enemy and press Attack. Your weapons will instantaneously be drawn out, and you will perform the stealth kill.

      Stealth kills

      You can get the different stealth kills by being in the correct position in relation to the enemy.

        Easy stealth kills

        Sneak up from behind.

        Sneak up from behind and crouch.

        Jump on enemy, while pressing Attack in mid-air.

        Moderate stealth kills

        Sneak from the side.

        Hard stealth kills

        Sneak from front (or wait for them to turn around into you). Note: This must be timed perfectly.
