ive played halo since the beggining the only game i have not played were halo wars and anniversery but i heard you need to have terminals from CEA to unlock the terminals of H4 so i wont be able to get the raider armor and the aplha terminal
Calm down sport. I have heard nothing about having CEA for the halo 4 terminals, so I suggest you go online and search for locations and test them out. If you can not access them, then that sucks 
i heard you have to have a cod save file to even play the game.
internet rumorz is dumb.
