Actually, Bungie's obsession with the number 7 goes back much farther than Halo. It is prevalent not only in Marathon, but also Myth and Pathways into Darkness. The Halopedia's list of number seven references is hardly complete. [url=http://marathon.bungie.org/story/seven.html][u]Here[/u][/url] is the section of the Marathon Story Page dealing with the number seven. [url=http://myth.bungie.org/legends/delusions/seven.html][u]Here[/u][/url] is the section of myth.bungie.org. One of the two most mysterious death messages from Pathways is "Seven men in overcoats jump from the shadows and carry you away. You are never heard from again." In Pathways, 7 germans died in the upper levels of the pyramid. There are seven different hyroglyphic wall sections on the level Lasciate Ogne Speranza, Voi Ch'Intrate. There is a potion hidden behind the seventh pillar on I'd Rather Be Surfing. There is a circle composed of seven Ghast corpses (which are piles of dust) on Please Excuse Our Dust. The bomb code is seven digits long. The origins and purpose of the number seven in the Bungie universe remain shrouded in mystery, but its presence and importance are indisputable because, after all, seven is darker.

It's the number of women Jason Jones sleeps with every night. Man's a legend...

To be honest, I don't quite know, I guess its their favorite number or something.
