No-scoping

No-scoping is the act of shooting an enemy with a Scoped weapon, but without using your scope. Learning to no-scope is a definite must for advanced players. It will indeed save you many times when a charging enemy must be quickly neutralized when taking the time to go to the scope screen will waste valuable seconds and likely result in your death.

Walkthrough
As with most Advanced skills, practice is essential to master this skill. So if you don't get it right away don't give up; just keep on trying.

When an enemy is approaching you with a Battle Rifle, M6C Magnum, or Carbine, don't waste time trying to scope. Just keep your cool and remember that you only need one shot, while they need a minimum of 7 rounds to kill you. Just line your Reticle at head level, and if possible, strafe left or right to line up the shot and fire.

That is the most common situation to use no-scoping. And since one of the best ways to counter a sniper is with the Battle Rifle, well it's a pretty common situation to find yourself in.

Arguments against No-scoping
Some say that since sniper ammunition is very rare in the Halo games, each sniper bullet is extremely valuable. Therefore, instead of wasting ammo on a charging enemy by using the No-scoping tactic, it would be better to switch to a Battle Rifle or any other weapon that can kill the threat without wasting sniper ammo.

However, while sniper ammo is pretty valuable, you want to keep the other team from getting your sniper. If you have to spend 2-3 shots keeping yourself alive, it's often worth it in the long run if you don't let the other team kill you and take your sniper ammo. The best players will never get into this situation as they won't allow the other team to get near them. Even if the other team spawns near you, you should just move to a better location.

It's important to note that until you've mastered No-scoping you should use another weapon.

Hints

 * When you are practicing, don't just keep aiming for their head when you are completely under control and in an easy situation. Practice under pressure, so when you are panicked you know you can handle the pressure. Also, try to shoot them once, then melee. This is the best way to do it since you use only one shot and still get the kill. It's easy and doesn't waste ammo.


 * Another strategy for no-scoping is jumping. Instead of taking the time to line up the shot on their head, get the target on the center of their body and jump. Pull the trigger as it passes their head on the way up or on the way down. It's almost like face painting but with no auto. It works most of the time, as long as they don't move.


 * No-scoping is especially easy in narrow corridors, as well as effective. Sometimes players will take a shotgun into a narrow passageways and just charge you to get close enough for the fatal shot. No-scoping with a sniper rifle is a great countermeasure to this technique. This is especially true for the Shotty tunnels on Sanctuary (Level).
