(even though Jun was a horrible shot), and one time he played he only killed two grunts, and he shot me in the head twice, because he was firing the wrong direction. After Jun betrayed me twice I pushed him off a cliff a few times.
The cave of a thousand faces is a cave found in the halo 3 mission arrival. to get to it you have to wall jump out of the map. once youre outside the map and walk a while you see a cave and if you jump into it you see all kinds of things on the walls of the cave. I might not be the best describer but you can see it on youtube. Me, having done this have seen only "7" and the face of a dog.
the jumping through the holes in countdown theory was made because on bungies site a picture showed a bungie employee going through one of the holes on countdown. this was posted on bungie day, by bungie. And some of you might know that the BOB helmet was spotted on bungie day. so that is where that theory came from.
I really don't see that as an easter egg of sorts. I would call it more of a creative perspective. I bet if you look hard enough in other places, your brain could make you see more things that are not intentional.
