Weird hands

Have a friend in Forge mode. When you start the game, spawn a Brute Shot. Have the player who is not the host turn in to a Monitor. Have the host remain a player. Have the Monitor look at the Brute Shot as if they are going to pick it up. Have the player look as if they are going to pick up the weapon. Do a countdown and have both players take the weapon at the same time. This may require a few attempts.
Penguin Man
When doing the "Weird Hand" glitch, try shaking the weapon. It will make the person's arms disappear.

Invincibility

You need to have a partner and be in Forge mode. Have a friend or yourself host a game. Have the person who is the host be a player and have the person who is not the host play as the Monitor. Spawn a weapon like a Brute Shot. Have the Monitor look as if he or she is going to pick it up. Do the same thing with the player. Do a countdown and have both players pick it up. On the Monitor's screen, the player's hands should have no weapon. However, that player should see the weapon in their hand. While the Monitor is still holding onto the weapon press RT and the player's arm should be ripped off, or press Y button to delete it. This may require a few attempts.

Floating objects

While in Forge mode, you can make a weapon or possibly an item float in mid-air. First, create an item. Make the top of the item flat so that you can place a weapon easily on it. Place a weapon on top of the item. Then, go to the item that is holding the weapon and press Y. Note: Do not press A then Y. The item will be gone, but the weapon will still be floating in mid-air.

To make objects stay afloat, you must have two players in Forge mode. Have one person must spawn a Receiver Node (teleporter). Have the other player spawn an object that they can carry when the teleporter is dropped on it (for example, a crate). Make sure the Receiver Node is upside down when placed on the crate or other object, otherwise whatever you place on the teleporter will be slanted. Once the teleporter is on the box for at least ten seconds, get rid of it. After that, the teleporter will float. Uou cannot stand on it, but you can place objects on it.

Endless fireworks

Enter Forge mode on any level where you can place both fusion coils and propane tanks (High Ground and Last Resort recommended). Place as many fusion coils as possible. Turn their run time minimum to the amount that you have placed. Do the same with the propane tanks. Make sure they are within close range of each other. If you shoot a fusion coil or propane tank, the explosion will set off any other propane tanks. When the other explosives respawn, the propane tanks that are currently flying around will usually detonate the fusion coils that have newly spawned.

Construct: Go under map

To do this trick you must be in Forge mode and be at Construct. Make sure you sell a respawn point before doing this glitch. Start out as the Oracle. Go down the pink grav lift by using your boost (press LT). There should be a few holes. You cannot fit down these as the Oracle. Start boosting into one of these holes that is not a closed circle. The Oracle should go slightly lower into this hole. Make sure you keep holding boost then turn into the player (either Spartan or Elite). You should fall underneath the level. Make sure you drop a respawn maker on a place where you can stand. This is to allow you to back there whenever desired. To prove you are under the level try to fly up without going through the grav lift. There is an invisible wall just like in the Foundation level in Halo 2, except on the bottom. This may not work on the first attempt.

Covenant: Two Arbiters

Play the mission alone. When you have exited the third tower and killed all the Flood, there should be a group of Marines waiting in Warthogs and Tanks. The Arbiter should enter a Phantom and start to leave. Get in the Scorpion and destroy the Elite Phantom. The Arbiter will survive and fall on the slope below. Get in a Warthog and have the Arbiter jump in the back. Continue the level as usual. The Arbiter will accompany you even though he normally is not there. After destroying the two Scarabs, the same Phantom you destroyed earlier should spawn another Arbiter on the ledge where he normally calls for you. The original Arbiter should still be in your Warthog. Drive the Warthog on the side of the ledge until you reach where the new Arbiter is standing. The Monitor will activate a light bridge. Both Arbiters will now enter your Warthog. You can now drive both of them around. Note: After the intermission sequence with the Prophet and Johnson, only one Arbiter will be there.

Halo: Unlimited Spartan laser

Use the following trick to get an unlimited Spartan laser on last level "Halo". Play through the level until you meet up with Sergeant Johnson. Shoot him until he falls down and drops the Spartan laser. Quickly pick it up and shoot it at him. Keep shooting him until he kills you. When you respawn, knock him down again and pick up his laser. He should get back up with another laser on his back. When he does, shoot him down again and pick up the new gun he drops. This laser should have unlimited Spartan ammunition. This makes it easier to destroy the Guilty Spark 343.

Highground: Leave level boundary

To get out of Highground you must be in Forge mode. Go down to the beach area and get in a Mongoose. Have the person in the Mongoose accelerate at the barrier. Afterwards, have the Wraith boost at the back of the Mongoose from a short distance. For a brief moment the Mongoose will be past the barrier. When this happens, get out. You will then be outside of Highground. This trick works in all ocean maps.

Highground: Killed by guardians

At the first camo spot in Forge mode is a ledge that resembles a triangle. Go into Monitor and push into the ledge. You will be killed by guardians. Note: This may require several attempts.

Isolation: Leave level boundary

In Forge mode, get as high as you can as the Monitor. Spawn a teleporter on the ground. Then, hug any wall still as being as high as you can and spawn another teleporter. If the teleporter beneath you is lit up as it should be, turn back into a Spartan or Elite and go through the it. You should now be outside the level boundary.

Last Resort: Stretchy Master Chief

Enter Forge mode and select Last Resort. Move to the two Mongooses next to the building on the far side of the map from the beach. Change into the Monitor and place six or more Fusion Coils near the side of the bridge coming out of the building. Change back to Master Chief and stand on top of the coils. Position yourself so that when they detonate you will fly into the side of the bridge. This may require a few attempts. Then, end the game. Go to the theater and watch the movie. Play the explosion slowly by tapping A quickly to pause and restart the movie. If done correctly, upon impact Master Chief will stretch out.

Last Resort: Invisible bridge

Set the speed and gravity to the lowest value and start the game. Stand on the wheel in the middle so that one of the arms will raise you up. When you are high enough so that you can start walking up the arm, walk up to the center of the wheel. You will see a hole on the round wall in front of you. The hole has some black wires hanging around it. Crouch jump into this hole. Keep jumping straight up. In a few jumps you should be able to squeeze between the wires and get on an invisible bridge. This makes an excellent sniping point.
