Halo 3 Hints

When fighting the flood, if you carefully shoot their arms off without killing them, they will follow you around harmlessly without killing you. Its kinda like having a pet flood. USE THEM AS DECOYS :D

In forge go to sandtrap were there are elaphant (2) turn to the moniter and buy a tank and try pushing it not to close.Once you flip it there will be a note on the upper side of the screen.

When you are on the first level srry dont know wat its called you kill all of the grunts you will go where youll go where you kill a jackel and you will see like monkeys with teddy bears good luck finding

There will be a dead marine that has a teddy bear in his hand on the first level(Siera117).It is near the checkpoint called Charlie Foxtrot.Also I did this on legendary mode so I think its only on Legendary mode.

First go 2 forge.(u need at leest 2 ppl 4 this) spawn or find mongoose. have 1 person drive and 1 person ride. driver gets of and enters forge mode. (2 do this u also need 2 shut of the gardians by throwin trip mines until the explode. 2 do this correctly spawn 2 then find the other 2. go 2 item settings. set runmin 2 1, and runmax 2 4 and respawn 2 10 secs.) push rider out of map radius. the rider now gets of as oracle still holds the goose otherwise u get pushed back in2 map.the rider now spawns a recevr telport and the other spawns a sendr telport. enter the sendr and ur uot of the map. go out 2 fr and ull die. make sure evry1 dies at the same time then end the game. then go 2 thetr an when evry1 dies go 2 the towr to the right of the ship. go srtate 2 the top. slowly go down and when u go down far enuf u should see the egg. take a snapshot of it and put it in ur filsher so evry1 can see it. HAVE FUN!!!!!!!!!!!!!!! :-) :-)

The Heroic map pack is free and has foundry which is the most commonly used map on forge and on foundry you can build houses PLUS is very fun.

IT IS A SKULL THAT GIVES U MORE GAMESCORE WHEN U pick it up. go on the lever the storm at start. go thru the tunnes and bluildings till u get out in a big open erea. u will see 2 wraits. dont destroy them. if u do the skull will go away.u can only kil the gunner not the driver. u will see a round short building. get a worthog and drive next 2 it. crouchjump on 2 the building. the skull is ontop. press rb to pik it up and get an attchevemant

Start at metropolis level and go to the door with the blinking light and jump on the look on your right and jump on that light and crouch jump on the roof then keep moving and then you will find it

Notice how some of the human guns kinda look like guns in real life. Here are the ones I know:
Magnum-USP .45
SMG- Mini Mac 10
Battle Rifle- Famas G2
Sniper Rifle- Barrett M82A1
Shotgun: Remington 870
