This will give you a bonus multiplier for coop & go towards earning the Guerrilla, Demon, etc. achievements.

Black Eye Skull

From there, jump to the red cross beam then up onto the pipe. From there, just walk to the end. Walk over the Black Eye Skull to claim it. You do not have to pick this skull up, it does it automatically. Its description reads "Bash your way to better health." Your shield will not auto-recharge anymore, and you must kill an enemy with a melee attack.

Get Underground in Construct

You have to play Forge on Construct. First, go to the pink lift (either one). Then, turn into the monitor and go down the lift to the bottom using the turbo (LT). Once at the bottom, you should see a hole type thing that you can't fit through as the monitor. So, while holding turbo the whole time, turn back to Spartan/Elite mode. You should fall through the hole. You can walk around down here, but you can still fall off and die.

*NOTE: Once down you cannot get back up unless you commit suicide.

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.

Floating objects

To make objects to float in Forge mode, make a tower out of two way nodes and crates. Then, delete everything except the teleporter under what you want to float. Make sure the tower ends with a two way node. This requires some time, but if done correctly you can make floating buildings that do not fall when you touch them.

Valhalla: Leave level boundary

To leave the level boundary, you must be at the ocean barrier (the side with the ocean). Once there, you and your friend must get a Mongoose and a Wraith. Have your friend drive the Mongoose into the barrier. Keep accelerating and have somebody get in the Wraith. Drive behind the Mongoose inside the Wraith and use the boost. You must be close for the Mongoose to go through. Once you hit it, your friend must jump out once he sees it pass the barrier. You are now outside the barrier

Last Stand: Float

On the map Last Stand (Zanzibar) you can float for a little while above the ground. To do this, go into the Forge lobby. Press X and adjust the player movement settings as follows: Speed -200% to 300% Gravity -50%. Start the game when you are finished. Go to the beach. Get to the archway where the vehicles go. Turn and face the beach. You can either have someone go straight until they hit the invisible wall in the water, or take a guess. Either way, run towards the ocean. When you are about halfway to the person press A to jump in the air. When you hit the invisible wall you should float slowly down, then begin to hover just off the ground (almost as if you are walking on water.
