in halo 2, what is the "noob-combo"?

Answer 1

2.7 THE ART OF THE "n00b COMBO"
------------------------------------------------------------------------------
-The TRUE n00b combo is the Plasma Pistol with the BR (interchangeable, of course).
-The stereotypical name is merely an opinion, and mostly a lie. The n00b combo is truly only effective on people who are careless, aka, did a n00b mistake. Soyou walk out in the open...what happens, you get smacked by the combo, and get
ticked off and call it n00by, because you were n00b enough not to stay in the shadows.
-In the hands of a n00b, the n00b combo can only work on other fellow noobs, and only about 1 out of 10 times on more seasoned players. It takes a seasoned player to take down a fellow seasoned player...no shortcut will get you there.
-If you don't use it someone, someone will use it on you...simple enough?
-IF YOU DIE USING THE N00B COMBO, YOU WILL BE CALLED A "NOOB." Make sure if
you're chances of pulling off a successful n00b combo kill are low, retreat, and spare your dignity.
-It is best to attack those unsuspecting, like a scoped sniper looking for your other teammates, than a person looking at you with a rocket.
-The Art of the n00b combo is that it requires proficiency, accuracy, and planning. Effective timing will prove flawless, and being able to hit the headshot everytime will truly show your mastery.
-Three Keys to Mastery of the Art of the "n00b Combo."
1. Make sure opponent does not have an opportunity to escape headshot kill, by running behind a rock, or turning a corner.
2. Release overcharge and switch and aim for the perfect headshot.
3. At the same time of overcharge impact, pull trigger.
-The most proficient killers using the n00b combo will kill an opponent during the opponent's graphical/visual hallucinations (put in by the game creators) that befuddle opponents for about a 1/4 of a second.
-The n00b Combo is effective at sniping opponents out of vehicles. Make sure you time the PP overcharge projected path correctly though, because this requires more skill than just a walking person, and make sure the vehicle won't be able
to fly away from the line of sight of your reticule.
-The other combos are considered n00b combos as well, but they are not in my opinion: PP and Carbine - superior, but with a one shot discharge compared to the BR's 3
shot burst discharge, the Chance to Kill is slightly lower.PP and Magnum - perfect for taking out 2 to 3 unsuspecting opponents, but lacks in range, and hinders those who are trigger happy and use a clip up after only one kill.

*Update*
Bungie has added a n00b combo game called: Combo Training. You can find it in Team Actionsack, and it's nice to test your skill at this, especially when masters go all out on this combo that most people can use...but can you use it well when faced against expecting non-n00bs?

*Another Note*
-When trying to shoot people out of vehicles via the n00b combo, make sure when you release the PP that they are not facing you, since most of the time, the front of the vehicle will protect them. Side shots are the best.
-This is obvious, but the n00b combo is ineffective versus tanks and wraiths.

Answer 2

Halo Noob Combo

Answer 3

While playing in a Halo 2 multiplayer match, especially Xbox Live (haha), the "noob combo" is as follows:
-While using the plasma pistol charged to full capacity, fire that round and hit an opponent. Quickly switch weapons to the Battle Rifle and fire off one burst into the opponent, therefore ending his/her life.

Answer 4

when you charge up a plasma pistol, shoot it at someone, then quickly switch to a battle rifle and shoot the person you shot the plasma pistol at with it.
