If you've played destiny for a long time or know bungie well, you will know that they love the number 7. Destiny is 7 letters, bungie day is on the 7th of the 7th, 7 coins hidden around the map, ect... So if you go to the tower, on the way to the tower hangar, you go through that corridor. On the right wall somewhere along that corridor, a few guns are hung up. However, if you look closely, you will see one is missing, meaning there are seven guns. Is that coincidence or another 7 easter egg? Sorry if this has already been found, I noticed this today.
