Im txgrim4 (Grim, Grimmy, Grimsta), i have been playing xboxlive for 9 years, evr since day 1 of Halo:CE til now. I love H2, that and Halo 1 are my favs. Im a Halologist when it comes to the Bungie/Halo Universe. Ive also played Marathon Series, ONI, and Myth Series. I live in Texas, Play Football, and cant wait for Halo 4!
I was going through the Halo 4 Teaser Trailer scene by scene, looking for any odd or hidden things, the one I found is not much, but its something. In my opinion, it is a Halo Ring on a moniter screen, to some it may not be, take a look-> Its where the red circle is
