Just shoot the hunter in its orange spot with a pistol and it wil automatically die.

on the maw after foehammer crashes keep going until you see a entrance to your RIGHT go in
the entrance and about half way through you'll see another entrance go in that entrance
you'll see a lone spec ops grunt(and alot of bodies) if you walk up to him he'll say "ehh
good thing that food nipples waiting for me on the starship cause man hoo! have i worked
up a big grunty thirst!" if you kill him before he's done saying his line his dead body
will stand back up and finish lol

The best way to kill a Hunter is using a sniper and aim it at the head but dont zoom its
gonig to take a long time and your going to get killed.If you dont have sniper gun or ran
out of ammo use a needler gun,roket lancher or a plasma grande turst me a tried it before.

on assualt on ctrl rm, about 13 mins in when you get the tank, get in a ghost instead.
drive through the tunnel and go where theres 2 hunters. the wraith tank will try and shoot
you but by mistake shoots its own team who folowed you in

DO NOT get the overshield in front of the well build, and when you get through the door go
back and get it, jump down 2 levels in the well and wait for shield to regen then look
over the edge of the bridge and see another overshield below. jump onto it and not only
will you survive but u will have 300% shields and be right opposite the cartographer.

ENJOY

Get on the Warthog and drive in to a wall and get out where the Warthog was will be a dent
in the wall in till it has

MUST HAVE FULLY CHARGED OVERSHIELD
  When on The Silent Cartographer, you can skip a good amount.  When you trigger the
cutscene after going down the locked door, you can look down at the lower levels.  Use a
pistol and zoom in at some dead marines.  Now run and jump off the high platform and if
done properly you will land right next to your objective.
  NOTE:Doing this will cause you double the amount of Covenant badies including the
Hunters! 

You first need to be on the red team. then get any far range weapons( fuel rod and a
sniper is the best). (do the multiplayer in Blood gulch.) now, after you get weapons and
ammos, get in a banshee and fly to the edge of the high left side of the wall, towards the
blue base. There, you will see a rock that sticks out like a thick finger. there is a
little flat area, where only you, the rider can land on. drive your banshee slowly towards
the flat area (face the butt of the banshee towards the flat area) then look down so that
you don't get shot as much just in case the enemies sees you. Also, face the butt of the
banshee towards the flat area while looking down. then get off your banshee in that
position, and hope for the best. (when you want to get off, you can head to the left side
of the wall and try to slide down the wall. you will never get any damage)

when in maw there is a jump in the last check point try to get on that little brige. then
go through that right door with blood. look in the right you will find the name rex made
out of blood

In multi player levels, slowly back the warthog into a rock. get out of the driver seat
and go in the gunner seat. point opposite of the rock then get off. if done correctly you
will be inside the rock were people can't see you and sometimes cant shoot you

get in the banshee, back up the banshee to the thing in bloodgulch that looks like a
finger, but is the cliff, and go backwards to the lowest point in it and get out and you
will be up there.

at the title screen, press h,a,l,o,r,o,c,k,s, then you will have invincicility!!!!!

if you press p,o,i,u,y,t,r,e,w,q,l,k,j,h,g,f,d,s,a,m,n,b,v,c,x and z you will make some
ammo come out of your butt and it will explode and leave an endless crater. try it its
fun!!!
