Also Cortana sent out a distress message. She mentions it at the end of Halo 3 but that it could take years to reach. Its been stated somewhere that the beginning of halo 4 will start out with the distress message being transmitted to the Infinity it will also appear in the the Foward unto Dawn. Well at least it did in the trailer will Cortana giving her serial number and stuff.

What HALO installation's are we fighting on in the anniversary maps. Is is installation 04 or others?
