if you are battleing a elite with a sword,kill him ps dont bomb him and quickly try to get
his sword it kills them one shot!!!

You know the pesky action that the marines fire at you if you kill more than two of them?
Well, if you use grenades, they wil run away, but they wont fire on you. An excelent way
to kill them! :)

when the flood are out ther are some places wher the flood fight the covennt u should
whate till thay stop fighting then throw a coupl of grenads that should kill the last of
whots leaft in the aria it will save u having to kill both of the armes and loos health
and amo

if u press t,u,g,f,d,c,b,n,m,7,u,j,l,o a rocket will shoot out ur butt and make a huge
hole u will have to kill ur self to get out

  NOTE:Only works in NORMAL and EASY.
  When you're about to get your energy shield charged, instead of going under the thing. 
Go to the rear, and jump on the fallen canisters.  Get on the the walkway and jump onto
the energy shield chamber.  It ticks off the techie. 

this is good for pistol and sniper wen you see an opponent you need to move side to side
really quily whilst doing headshots and with da sniper wen they are moving to da left or
right aim a phew yarsd away where the possision thier coming at the quikly snip but always
move side to side and member be very very fast and have more fast and big movement

TO kill the flood u should probably NOT use melee attacks and don't go sticking a big
flood cause they will kill u as well, also u should stick to human weapons cause if u ask
me there the most suficient.

pfr plazma frag rocket through plazma then frag the rocket und the hog(person can be in
hog in multiplayer mode) and hog will go flying works on all execpt tank fun to
do!!!!!!!!!!!!!!!!!!!!!!!!!

If u  cant find ur friend in an outside place in multiplayer and u have a plams pistol
shoot in the air but dont talk to every 1 talk to ur teamates so the enmy ccant find u

When a banshee is fling overhead at u shooting at u, just bring out your pistol

and start shooting at the front, bottem or back and it should go into a ball of

flames and crash.

(make sure it does not land on you because it will kill you).

IN BLOOD GULCH ALWAYS GET A FUELROD GUN AND A ROCKET LAUNCHER THEY ARE THE STRONGEST GUNS
IN HALO GO TO THERE BASE AND STRT KILLING BUT AIM AT THE FLOOR NEAR THERE LEGS THEY WILL
GO FLYING AND USE A WARTHHOG TO RUN THEM OVER SO YOU WILL GET LOTS OF KILLS YOU CAN USE A
BANSHEE BUT ONLY FOR THE MAXIMUM OF 10 TO 16 PLAYAERS IF YOU GO ONTO A MOD WITHOUT THEM
VEHICLES THEN USE THE FUEL ROD GUN AND ROCKET LAUNCHER BUT JUMP WHILST YOU IN THE AIR THEN
SHOOT ITS EASYIER TO AIM NEAR

THERE FEET ITS COOL

in multiplayaermode at blood gulch go to te path with a sniper then suddenly press z twice
to zoom in aim at the head its takes one shot or 2 sometimes even 3 shots then your
opponent will be pissed off and think who was that but press Ctrl to crouch and then shoot
you will hav a great time trust me

ok so if you want to live the 2 big guys in the cartographer then heres how.



ok so walk in the room then you will find a sepret door then walk in there you will find
some cubes. these are sheld doubles. then walk back in the room. then thow a granade and
they willshoot.  as you see you will duck to live but! 1 thing.......though when you are
on target it wont effect them so you have to take cover in the roon and the best thiung is
to be in a tall tower of crap. cuse there retared the cant up the only shoot strat and
left and right so then take them out how ever you want. oh! and make shur you get thous
sheld doublers!

if an enemy has a sniper take  a invisibility thingy to hide no matter how hard they try I
allmost etirelly garanty they won't see u. But u are able to be seen up close so while
avoiding keep ur distance.

Hey folks, this cheat works in Single player as well as Multi Player or online play. 



You can melee twice in a row really fast. Just press (melee) + (grenade) + (melee) really
fast, and you will perform the double melee attack. 



You will also however throw a grenade, so watch out.
