Glitches

  • Easy Avatar Carter's Helmet unlock

    Normally, you'd have to complete a level on Legendary without dying to get this. However, you can play up until just before the end and "Save and Quit" on a checkpoint. Then, Resume the game and finish the level (without dying for those last few parts). After you finish, you should get the Avatar Unlock pop-up.

Easter Eggs

  • Easter Egg: Change Club Errera's Music and Brute Dance Party

    In Mission 7, you can change the music to the tracks "Never Surrender" and "Siege of Madrigal" in Club Errera. During Mission 7, once you get to the Club Errera part of the mission, head back to the hospital. Fly to a ledge below the usual entrance. If you chose the right one, when you get out you should see a green light. Once found, activate it and go back to Club Errera. Land and when you walk in the song "Never Surrender" will be playing. If you want to change the music again, go back to your Falcon and fly to the roof of Club Errera. Guess what, there's another switch. Activate it and the song "Siege of Madrigal" will now be playing. If you return to the dance club after you clear it out (Hunters included) then a Brute DJ will be spinning records, a Brute tends the bar and Grunts get freaky.

  • Master Chief Cameo

    Upon completing the final level (The Pillar of Autumn), you will see a cut-scene of the ship taking off. When the cut-scene starts, hold your aiming stick (it will be dependent on your control scheme) so that you would "turn right" normally. At the point when the UNSC shuttle docks at the Pillar of Autumn's landing bay, the camera will move to the right (if you were holding the stick to aim right) and catch a shot of a Spartan in a capsule. Should look familiar, right?
