Call of Duty Ghosts: The Aftermath

For seven Months after the end of the war against the Federation, when the replication of ODIN was fired on them and they fled, the Ghosts had everything under control. No worries, no Federation to deal with. The Ghosts, Merrick, Kick and Keegan, were all fine.
Well, except Hesh.
Logan was still missing. His baby brother. The one person in the world he cared about more than anything.
And he was gone.
But now, a new problem arises. The Federation is attacking again, and the Ghosts have more problems now than they had before.
And, at the center of it all, is Rorke.
With a vendetta against the Walkers.
