Noob Combo

The so-called "Newb Combo" is the combination of the Plasma Pistol and Battle Rifle, Carbine or Magnum. Often one would be walking and hear the splash of the plasma pistol being fired only to turn around and be hit in the face with the giant green blob and then shot in the head with the Battle Rifle, Carbine or Magnum in an instant. This combo was especially rampant on Beaver Creek and Colossus. It was incredibly effective and often turned the tide of games. This tactic was considered so imbalanced that Bungie attempted to remove it from the game by implementing the new Battle Rifle game type which removes all Covenant weapons from the map. This was largely ineffective. They also made a Team ActionSack gametype for it called "combo training"

Whether or not this weapon combination is actually a sign of being a "newb" is up for debate. While it is indeed a powerful and arguably imbalanced combination, it does require some skill to use, and using weapon combinations effectively is not a trait of a new player.

However, even a player who would normally lose to you can kill you at least once with it. The main distinction being that a skilled player will survive the counterattack and go on to get a spree; while an actual newb will easily be taken down once the initial surprise is gone and you know he's using it.

Combinations

 * 1) Battle Rifle and Plasma pistol
 * 2) Carbine and Plasma pistol
 * 3) Dual wielding Magnum and Plasma Pistol

Note: the newb combo is executable only with a plasma pistol and a close range headshot capable weapon. The SMG-Plasma Pistol combo is NOT a newb combo for the simple reason that you are unable to do a headshot. Anyways, this combo can be useful in campaign especially on the higher difficulties.

Blocking It
With a great deal of skill, patience and practice it IS possible to block the newb combo!

Here's what you do:

You MUST be dual wielding, and facing your opponent. Wait until the plasma discharge is about to hit you, then immediately press B, or melee. If done correctly, and properly timed, the plasma discharge will hit the weapon you just threw instead of you! It seems best to drop a Plasma Rifle.

A second method that can block the newb combo is to hit the discharged shot with a grenade. Plasma and Frag Grenades both work. Its argued that a plasma is better because it is a glowing ball of energy that the discharged bolt will home in on the grenade instead, while some believe that Frags are better because they fly through the air faster. The Plasma Pistol overcharge may also set off a Frag Grenade that is thrown at it, injuring the person attempting to block the overcharge.

Both the dual wielding and grenade method work and its about preference on which to use.

Survival can't be guaranteed, but it gives you an edge if you can master this slick move!
