Easter Egg: Lower Your Weapon
In a Local (offline) game, hold these buttons all at once for about 3 seconds to drop your weapon: LB + RB + DOWN (D-Pad) + L3 (click the left stick) + A
Unlockable: Mythic Map Pack Skulls
These skulls are found in the Mythic Map Pack expansion levels.
Assembly - You can find this on the central tower in Forge.
Sandbox - Fly towards the sunset and turn around to find this skull.
Orbital - At the place with two road blocks where you have to jump, this one is on top of the structure on the right.
Unlockable: Bonus Content
If you complete the game on Legendary difficulty, you can grab extra content off of Xbox Live, including pictures and a making of video.
Easter Egg: Spartan 117
When you beat the game, you will be shown a memorial for the men and women that died in-game. Spartan 117 is one of those considered KIA, but if you wait for the credits to end at the end of the game, you will see that Spartan 117 is very much alive (this only applies if the game is finished on any difficulty but Easy).
Hint: Custom Power-up Usage
The custom power-up you can add in the Forge will greatly make or break your game (depending on how many you put in your map and how fast they respawn). Since you can only adjust the custom power-up just before a match, be sure to jot down what effects you are looking for in a custom game.
Custom power-ups can only be used in Custom Games. Press BLUE to edit the match options in a Custom Game. Go into Weapons and Vehicles, then locate the Custom Power-up Traits. Have fun!
Hint: Plasma Burnout
If you don't have an Energy Drainer item, the plasma pistol's charged shot can be used to stop vehicles (but doesn't stop vehicle mounted weapons). Pack a plasma pistol when there are vehicles around; it's the next best thing to a rocket launcher.
Hint: Scarab Mangling
Having trouble with a Scarab? Or maybe you don't want to get on board (and abandon your bright, shiny Scorpion). Try this strategy instead: on the back of every Scarab, there is a circular glowing spot you can shoot to do damage (it is similar to the glowing spot on the back of Wraiths).
Locate the spot on the Scarab's rear armor that is below its rotating anti-air "ass" (or abdomen) turret. A few shots from Hornet missiles or Scorpion tank shells and the armor will fall off and reveal the critical system you normally need to board to wreck. Don't forget that shooting the Scarab's legs will stop it from turning.
Easter Egg: Elephant Flipper
In the Forge, edit the Sandtrap map and create a Scorpion. You can use the tank to lift and flip the Elephant (the large Sandcrawler vehicle). Once the Elephant is upside down (or undrivable), approach it to flip the vehicle and get a humorous message.
Unlockable: Hayabusa Armor
Collecting the three pieces of the Hayabusa Armor are collected by acquiring a certain amount of Skulls in the game. To get the Chest piece, collect six Skulls. To get the Shoulders piece, collect nine Skulls. To get the Helmet piece, collect all thirteen Skulls.
To unlock the Katana, which is a non-usable item that is essentially the fourth piece of Hayabusa Armor, get all thirteen Skulls in the game, and achieve a gamerscore of 1,000 (complete all achievements).
Easter Egg: Cavemen
On the Sierra 117 mission, the Pelicans will crash. After that, you should clear the area like you normall would. As the area narrows as you proceed, there are some rocks on your left that you can jump on. Continue along a ledge thereafter. Once it heads down, you'll pass a large boulder on your left. After you do, turn around and take a look where the wall and the boulder intersect. You'll see a family of primitive cavemen-like people!
Hint: Terminal Locations
You will unlock a secret achievement by finding all seven terminals listed below...
Terminals: The Ark
Go left through a door once in the very first building of the stage. The terminal is located beyond a curving passage.
A terminal is located right near the device that activates the bridge on this stage.
There's a secret room in the third building which holds the third and final terminal on The Ark. After you come across and kill a group of sleeping Covenant enemies, head down the nearby corridor. You'll reach a door that is locked if you do. To the left of the locked door is an open door. Head through the door, and then turn around to find the terminal.
Terminals: The Covenant
Head to the stage's first tower and stand on the elevator. Face the control panel, and then turn left. Jump over the obstacle, and find the terminal you seek.
Head to the stage's second tower and walk towards the entrance. When you come across a locked door, turn around to find the second of three terminals here.
Head to the stage's third tower and stand on the elevator. Face the control panel, and then turn right. Jump over the obstacle, and find the third and final terminal on the stage.
Traverse the first cave, and then head right until you come across a building. Walk along the passageway towards the building. Once inside, run left to find the terminal.
