Do not overuse the aim, meaning do not walk around aiming your gun everywhere. The problem becomes blatant when you walk into an open space and need to examine your surroundings quickly, so as not to get shot. Your aim speed is very slow. Instead, use the camera to look around quickly. Also, the direction in which you point your camera is where your character will aim his weapon when you press [Aim]. This is much faster than manually aiming. Finally, do not spray and pray.

After acquiring the instructor skill, enable it then do a salute. Your salute changes to a boasting type, where your character puts his or her hands on their hips and pushes their chest out.

Remain idle at the character selections screen. Your character will hide in a box or start reading a magazine.

Keep spinning your character in circles at the selection screen. When you stop, he will get dizzy and fall over.

Never stay scoped for too long. If you do, you will not be able to see your surroundings; if an enemy sneaks up on you, they will kill you in the most humiliating way he or she can think of.

Always keep claymores and magazines to alert you of the presence of an enemy that is trying to sneak up behind you. With magazines it is slightly more difficult, but it should be the primary choice only because while the enemy is occupied looking at the magazine you can easily get a headshot. Claymores will just knock them back, then they will get up and kill you.

When you kill an enemy from one vantage point, switch to another. Most of the time when you kill an enemy they will know where you shot them from, then they will sneak up behind you and kill you with ease. For example, at G.G. if you kill someone from the tower, get off the tower and run to the roof. By doing this they will not know where you are.

Never use the catapult. It is a sniper's worst nightmare when an enemy knows where you are. Almost every time you use the catapult, the enemy will know where you are going. They will then sneak up behind you and kill you.

Use tranquilizers instead of handguns. The Mozin-Nagant is not recommended. Use the Mk.II tranquillizer instead. If an enemy gets close to you, shoot them in the head with the Mk. II then zoom in with your scope (for about 400% more experience points) and get a headshot.

For easy headshots, shoot slightly ahead of the enemy. By doing this, the enemy will just run into the bullet. Make sure not to miss or you will alert the enemy to your presence.
