Hello, I am a part of section 3 on the HaloWaypoint forums, we are the ones that have decoded all of the codes in the ARG. Our wix site is: http://halo4arg.wix.com/section3-decryption
If you would like to take part in the ARG, or are looking for people to do LASO with, a few of the ARG members still have to do laso, So just pop in and say hello. Make sure to use your Halowaypoint name/Gamertag for your name so we know who you are. Link to the irc is: http://client00.chat.mibbit.com/?server=irc.webchat.org&channel=#halo4arg
It really doesn't look like anything all too special to be honest, but least you do get something from it. Apparently, you also get 50,000 EXP from unlocking it as well. So if you're not 130 yet, this could be a nice boost.
