THIS IS THE LINK TO ALL 10 CODES FOR ALPHA HALO ARCHIVE
I CAN NOT ENTER THE CODES APPARENTLY BECAUSE I HAVN’T PLAYED HALO ANNIVERSARY??
THE CODES JUST FLASH RED AND SAY SOMTHING ABOUT INSTALLATION 4??
IT SAYS YOU GET 100Kxp FOR THE CODES, DOES THIS APPLY TO ONLY REACH OR HALO 4 TOO??
PLEASE HELP ME FIGURE THIS OUT!
Jesus what is with the caps!? You need to find all the terminals first before you can use these codes and these just give you credits for reach not xp for halo 4
The Cr you get is only for Halo Reach.
There’s no need to yell, dude. I’m having the same problem. They’re right. You need to find the terminals in the game to be able to use the codes. It’ll be okay. We’ll get through this…would you like a hug so you won’t be yelling so much? 
so i need to play halo anniversary to unlock ALPHA HALO ARCHIVE?!
yeah i have to go back and find terminal 6 becaused i missed it at the end flood got in my way
