It is actualy possible because they could use the thought line that they are on reach which is THE main military outpost of the humans, and if they are on reach. Then atleast I believe that there would be one or two new wepons being developed at the time of the attack that were never released because of reach falling. Just a personal opinion.

I really don think that there could be any new guns because the game is before halo 1 (which also should mean no br)
