So similar to the vex? I can see them doing that likely will have troops destroying/guarding some huge weapon we have to destroy them that we lost control of covering each of the main ships.(I think the planets will come back I don't think they were destroyed. Asher had a experiment he shot the ships and found that even though it looked as though the projectile was gone it was just being held in place in a field) so I think we will be targeting the main ships. And take one out at a time. Then one on the city to win like how each expansion has been made since forsaken.
