DISTRACTION CAMERA
Whenever you see some enemies gathered, throw a Distraction Camera so
that they will not notice it. After you have control over controlling
the camera, continuously press the distracting whistle noise. The
guards will come over, but if not all the guards are there that are in
fairly close distance with the camera, then keep making the
distracting noise. Once some of the guards are over there, release the
gas. Sometimes the guards may just cough a few times, but not get
knocked on conscious.
                 
GAS GRENADE
This is an equivalent of the gas that is in the Distraction Camera.
However, this has a taller and wider gas range. Also, instead of
spraying in one direction, this is like a gas cloud. Whenever you see
a group of enemies, you will want to ricochet these off of a wall and
get it so that it's positioned near the enemies. It will burst open
and gas will fly out. Again, the enemies may not be knocked on
conscious. Usually, depending on how close you throw it to the
enemies, the enemies will immediately be alerted.

When using the sniper mode of the SC-20K, you can hold L1 to make Sam hold his breath and aim more accurately. You can use this to clear out rooms or open areas from afar without letting anyone spot you. The safest way is to wait for a guard to stop in his tracks. Then, hold L1, set the target on his head and take the shot. This is extremely helpful in the first few levels from when you pickup the SC-20K. However, when you get to the Abbatoir mission, you must be extremely careful as the guards can see you from a lot further, can see you in the shadows, and also have more powerful weapons. You must exercise extreme caution. From Abbatoir onwards, if there are multiple guards in the one room, your best choice of action is to use a smoke grenade, if they are bunched up. If not. then do not go in commando-style because the guards from here on out are much more powerful than in previous levels.
