Seven



Bungie Studios has long enjoyed using the number seven in its games in as many ways as possible. Therefore, in many of their games, this eccentric idea has caused a wild hunt for as many references to the number as possible (even if they are unintentional).

All of the Halo Series
In Halo 3, to unlock the IWHBYD skull, you must jump through 7 rings in order to make the skull spawn.
 * Seven rings
 * Seven Monitors
 * HALO: In the English alphabet, H = 8th letter; A = 1st letter; L = 11th letter; O = 15th letter. 8 + 1 + 11 + 15 = 35. 35 is a multiple of 7 (35 / 5 = 7).
 * In Halo: Combat Evolved, you fight on Installation 04. In Halo 2, You fight on Installation 05.  In Halo 3, you fight on Installation 04 (II). 4+5=9 9-2=7.  Or 4+5=9 9-4=5 5+2=7.
 * In Halo 2, to achieve the IWHBYD skull, you must defeat 7 waves of Ultra Elites.
 * When you add all of the installations' numbers(0+1+2+3+4+5+6+7);the answer is 28. 28 divided by 4 equals 7. 0+1+2+3+4+5+6+7=28/4=7

117
117 is Master Chief's SPARTAN tag number, but there is more than meets the eye when it comes to this number, including many religious and historical references.

Biblical Reference

 * John-117 is believed by many fans to be a reference to New Testament of the Christian Bible.


 * Bungie Studios is known to have placed many biblical references in their earlier Marathon video game series, and many other such references have been found in the Halo series.


 * Here are passages from the Book of Revelation (more formally known as The Revelation of St. John the Divine). Revelation in Greek is called "The Apocalypse", a title possibly shortened from "The Apocalypse of John."


 * "And when I saw him, I fell at his feet as dead. And he laid his right hand upon me, saying unto me, Fear not; I am the first and the last: I am he that liveth, and was dead; and, behold, I am alive for evermore, Amen; and have the keys of hell and of death."
 * Book of Revelation, KJV. Chapter 1 - verses 17 and 18.


 * "And when they shall have finished their testimony, the beast that ascender out of the pit shall make war against them, and shall overcome them, and kill them."
 * Revelation. 11:7


 * There are also references in one other book of the Bible. 1 John houses these:


 * "But if we walk in the light as He is in the light, we have fellowship with one another, and the blood of Jesus Christ cleanses us from all sin."
 * 1 John 1:7 (1 John 1: 7)
 * "And the world is passing away, and the lust of it; but he who does the will of God abides forever."
 * - 1 John 2: 1 7


 * And here are passages from the Gospel of John. These are thought less likely to be references:


 * "Then after that saith he to his disciples, Let us go into Judea again."
 * Gospel of John, 11:7


 * "For the law was given by Moses, [but] grace and truth came by Jesus Christ."
 * Gospel of John, 1:17


 * Halo 3's plot also resembles Noah's Ark, read the terminals if you haven't realized it.

Site 117
Alternatively, others believe the number to be a reference to "Site 117", an archaeological site containing the first evidence of a human battle. The site is near Jebel Sahaba, Nubia and dates from between 12,000-10,000 BC. The site contains 59 human remains of men, women and children who were clearly killed with primitive hunting implements.

117 and 7
Seven has long been a number associated with Bungie. The first three numbers of 76 are 117, the full number being 117649. Also 1*1*7 = 7 and 1+1+7+6+4+9=28 28/4=7.

The 7th Halo' Monitor code is 117649. Maybe the 117 is significant because it's the 7th Halo, however the 649 could be significant as well. 9+4-6=7. Also, 117649 = 76

The number 819 appears numerous times in the Marathon series. 819/7=117.

Marathon
In Marathon Infinity there was a hidden multiplayer map called Hats Off to 819 (named after fan Hamish Sinclair, H=8, S=19) 819 divided by 7 is 117

117 Trivia
In Halo 3, the game won't let you input the I.D. tag "I-17" or "l (lower-case L)-17" saying that these numbers are already reserved by the UNSC. Additionally, "E-43" a variation of 343 will have the same result.
