Crouching
To crouch, click and hold the Left Analog-stick.
When crouched you will not appear on motion-sensors. This is helpful
in multi-player mode when you do not want the other team to find
out where you are.
Illegal service tags
- If you go to "Appearance" and try to change your service tag to "I" or "L" followed by "17" (for example I17 and L17), it will result in a message that they are reserved by the UNSC (Master Chief's number is 117). Also anything that ends with "00" will result in the same message. Entering "T17" and "A55" will result in a message stating that the service tag is not allowed under current UNSC regulations.
, , and
- If you try to use "F46" as your service tag you will be told that it cannot be used under UNCS regulations and rules. It is interpreted as an offensive three letter word for same sex relations.

Delete emblem
You can delete your emblem by putting the seventh column as your main emblem, blank as your background, and pressing X.
Easy Legendary mode
When starting a campaign, insert a second controller and gradually move the person forward to prevent starting at checkpoints farther back in a level. This is useful when you do not have Xbox Live and no actual second player to help.
Play as another character in Campaign mode
At the main menu, press Start and a screen will appear. Press Right and select "Appearance". You can now select what kind of character you want to play.
Getting in the same ranked Lone Wolves game
Go to your Dashboard. Change your language to the second option from the bottom. Start Halo 3. Invite four other friends that are about the same rank as you. Also have them change their language to the same one as you. Get everyone in the same party before you want to get them in the same party. Everyone must search at the same time. Everyone then must make a game in Lone Wolves. Before you go to start the countdown, press X to change the search options to the bottom one, which is to search for the same language. If done correctly, chances are you will be in the same ranked Lone Wolves game as your friends. You can now get achievements or level someone up.
Always Human on "Living Dead"
While playing on "Living Dead", you can become human every time. After all players are found for the game and it starts, the screen will turn black for a few seconds. Press RT at the last moment and you should hear a shotgun sound. You will be human. This works in every round of the game. Note: If you have two or more players, they cannot both use this trick. However the other person(s) will still have a 50% chance of being human.
Be the Oracle
Press Up at the Forge lobby and you will turn
into the Oracle. You can pick up items by pressing A when
you see a green hand.
At ease position
Note: The following can only be done in a local match or replay. To do the at ease position you must hold LB + RB for at least three seconds and press Left. If done correctly, your weapon will not be visible on your screen. When you shoot you will raise your weapon again.
Stealing Wraiths
Usually when you want to steal a Wraith, you will blow it up instead of stealing it. This trick works best with a Brute-spiker. Press A to jump up on the Wraith. Do not press RB. When you are on the Wraith, do a melee attack to kill the Brute behind the turret. Afterwards, look down to see the driver door. Do two or three melee attacks on the door until it opens. You will then see a Brute sitting inside. Do not shoot him or the Wraith will explode. Instead, do some melee attacks on him until he dies. When done, the Wraith will be slightly damaged but will still work perfectly.
Steal an Anti-Air Wraith
At least two players are required for this trick. Go to any level where you can reach an Anti-Air Wraith and kill the person in the turret. Then, have one player board the Anti-Air Wraith in the front. Have another player jump on the front part of the Wraith, holding RB. Then, have the person who is boarding the Anti-Air wraith punch slowly. After two or three punches, the pilot will die but not the Wraith. The person holding RB will be in the Anti-Air Wraith. Note: If you get out of the Anti-Air Wraith, it explodes. If a person is in the turret, there is no crosshair.
Destroying vehicles
This trick requires a plasma pistol, Spartan laser, power drain, plasma and spike grenades. For ground vehicles, use the Spartan laser. For fast ground vehicles, use the power drain on them then use the Spartan laser. When fully charged, the plasma pistol acts like a power drain. It will help with Banshees, Hornets and Phantom Turrets.
Stay zoomed in
If you are zoomed in as a Spartan or Elite and turn into the Monitor, press Up to turn back into your character. You will still be zoomed.
Brute Chopper wheels
All Brute Chopper wheels are actually in the shape of a Brute head. Look at it from the side and you should notice that the steel containing the wheel is shaped like a head of a Brute.
Avoiding The Flood
This trick is only useful when inside the crashed Flood ships, for example during the mission when Master Chief goes in with a Banshee (the mission before the "Halo" mission). Infection from Flood can bring dead Flood back to life. To avoid the "infection forms", be careful not to shoot the bubble-like objects on the walls. They will blow up and release many infection form Flood. The small ones can release five to ten infection forms. The big ones can release ten to twenty infection forms.
Smarter respawning
When playing in Co-op under the Legendary difficulty
setting, it is best to have one player keep their distance from
the enemy at all times. By doing this, if the rest of the players
die they will respawn around the player that is farther back,
rather than having to restart the checkpoint.
Complete Legendary mode easily
If you are alone and need to complete Legendary mode, turn on an idle second player to stay behind. If you die, you will respawn instead of restarting.
Veteran's Day reference
Set the Xbox 360's system date to Veteran's Day (November 11). Go to "Custom Games" and the Valhalla map. Take a Banshee to the middle of the map. Go to the opposite side of the crashed Pelican. On the huge dam-like wall, there should be a message directly in front of the Brute Shot stating that "Kilroy was here" in a white font. Also, if you face the wall, turn right, and walk towards the rock in front of that base, you will see the same message (with the same picture) under the grass.
Development team reference
Go to "Custom Games" and play the Last Resort (Zanzibar) map. Go to the area to the right of the windmill (with the sniper and fusion coils). There is a plaque on the wall directly ahead. It reads "Camp Froman" and shows a man with messy hair and glasses. It also shows a sniper rifle under "Camp Froman". "Froman" is the nickname of one of the Bungie employees, who made the location originally on Zanzibar and moved it to Last Resort as well.
Red vs. Blue reference
Find any Warthog in Custom Games or Forge modes. Look at the rear left hubcap. To the right of the hubcap on the wheel, it very faintly read "Puma", referencing Grif's comment on what they should call the Warthog (a.k.a. Chupathingy) from season one immediately after Caboose and Donut arrive.
