Okay folks a very cool Easter Egg has unfolded. Besides watching the terminals in Halo CE: Anniversary you can earn credits by unlocking them on Waypoint through the XBOX.
Here is how. First watch a terminal you have unlocked. At the end you will see a sequence of symbols like in the following pic (this is the terminal for the level “Halo”):
Write these down, then go to Waypoint on your XBOX.
Press start and you’ll go to the normal screen:
From here do not go any further. Instead press the “X” button on your controller. You will then go to a screen with a series of colored circles:
Those represent the color buttons on your controller. They are random so don’t enter the ones you see here, enter the ones you see on your screen. Enter them left to right. Don’t worry about if they are higher or lower on screen, that doesn’t matter. Just left to right.
If you do that correctly, then you will go to this screen:
This is the master list of Forerunner glyphs. Enter in the code from the terminal that you wrote down. Note: You MUST unlock the terminal in the campaign first for this to work. If you enter in a code you found elsewhere you will get an error saying you must first find the terminal in the campaign (so you can’t cheat and look them up on YouTube).
As you can see the code is entered and you just need to go to the bottom right to complete the entry. Once done properly you will see this screen:
Note that the Forerunner glyphs are now brighter blue. From here you will go to another screen showing the terminal you unlocked. When you do this for the first time for each terminal you will earn 7K credits (for each terminal).
Once you’ve found all 10 terminals in the campaign and unlocked them on Waypoint, you will receive an additional 37K credits AND a special 11th terminal that can’t be accessed through the game.
