first off all get a shotgun then shoot the flood one shot should get rid of one but if you
do a well aimed shot then you will kill more

visit www.halomods.com and download a devtrainer open it and extract the file after that a
red NC helmet with a purple visor shows up click on it and click run  allows you to:

notice its not my mod have fun modding only for pc

XD

when ever you find a wepon chances are thier are more of it conserve your weapon if it is
a good weapon

now, if your on the multiplayer bllodgulch map, make sure there is no friendly fire
on...and get a buddy to get in one of the bases, next, (not in main place where u get
flag) get in a corner, get your buddie to run you over into the wall behind you,
eventually after a try or two, you will be falling

(only flaw is that you must change teams and then go back to your team to get OUT of the
underworld)

when you get to the level with the flood don't waste the ammo on the little ones because
they cant infect you your suit is to strong. Plus you should save it for the bigger guys
who can get guns.   

  P.s. the human infected flood come back up after you kill them wit no weapon so just hit
them and they'll die.

Go to any level with large flood in it. Then avoid there gunfire and shoot there arms off
and you can shoot there head off to as long as you didn't fire at them or do any
damage.That way they can't hurt you. make as many as you want but be careful not to shoot
them or let them get hit by covenant or marines sentinils. this DOES NOT WORK ON ANY OTHER
FLOOD including those sacks of popcorn flood

first throw a plasma grenade then throw a human grenade in front before it explodes the
human grenade will go of flying

on a level with needlers AND hunters such as the silent cartographer grab a needler and
aim at the first hunter you see unload a full 2 or 3 clips into him and he will explode.
aim for the orange flesh or BLUE armor the needles bounc off the shield.

get any weapon that has singlshot (except rocket launcher,shotgun and sniper rifle) weaken
the elite,s sheild then shoot under the blue armor on the knea hell bend down for like 5
secs go up the him throw a plasma grenade on back of his neck,nose,eyes,butt,back
anything!!

flood can come back when killed to stop that destroy the body melee it certain bodies
cannot be destroyed when u hit a body itll break into fragments and youll hear a creepy
scream

first get a hog no matter wich kind then put the back of the hog against a rock one in
shoot your enemys explosions wont get in (if you cant get in try from differnt angles) the
only flaw is that you might not be able to get out

if a friend has a rocket launcher in multiplayer then ask him to shoot you but make sure
it is a freindly fire game soon you wil be flying through the air

if you have something to kill it do it now hear is a fast way to kill banshees throw a
gournade    at it and it will take 1 or 2 hits to  shots..

you'll need 4 fragment grenades,4 plasma grenades,a warthog and a rocket launcher.go to
blood gulch or any place with a cliff on any mode and park your ride under  a cliff.then
throw two(or more) plasma grenades at the machine gun part of the warthog.then throw
two(or more)frag grenades at the machine gun part of warthog.then shoot a rocket (with
your rocket launcher of course) to the machine gun part of warthog and watch you fly.
