Sorry I can't post a proper URL Im on mobile but people in the waypoint forums along with others on the internet have cracked an interesting code revolving around Halo 4 and its companion app Halo Waypoint. In short the reward for all this hard work is a secret set of armor and 500xp. Pretty interesting!

Thanks for the heads up. I was trying to read about this on the waypoint forums but couldn't figure out what they were talking about. Jump right on this when I get home tonight.

Link doesn't work and I'm on my phone. Will check it out later. Thanks.

I get the message I don't have all the requirements when I enter the codes.

Didn't work for me either, I heard you may have to beat the game, spartan ops, or find the hidden terminals....so it could take awhile.

It worked for me but I've already beaten the game, a couple Spartan Ops missions and found 2 terminals.

Anyone figured out the helmet code yet?

I've beaten the campaign but nothing else and it didn't work.

I believe your Spartan Rank needs to be high enough for you to claim these rewards.

Complete the first two or three Spartan Ops missions and it should get you high enough that you can unlock these codes.

The oni code worked for me. i need to play Spartan Ops and access the terminals to unlock the others.

In case anyone hasn't found it yet the code for the helmet is here: https://forums.halowaypoint.com/yaf_postst133952_Raider-helmet-code.aspx (on my phone so I can't make a link.) All you need to do is finish the third spartan ops mission then enter the code in Waypoint.

Not sure what it does exactly but you need to find all of the hidden terminals for it to work.
