I put the code for Wiseguy but it didnt work, I saw a message but it didnt stay up long so I couldnt read it.

What do I have to?

You have to have found all of the Terminals in the Campaign, I believe.

Just to be clear, to get the helmet, just play the Spartan Ops, right?
I unlocked it all (Terminals, Halo CE Terminals, connected the codes etc.) My bro wants it.
