"Infiltrate the weapons factory to find out what the Federation has been building."
— Mission Description
"End of the Line" is the thirteenth campaign mission of Call of Duty: Ghosts. The mission involves the Ghosts storming a factory occupied by the Federation to find out what kind of weapon they are building.
With the LCS at the bottom of the ocean, nothing stands between the Ghosts and the weapons factory. Elias sends in all five Ghosts to the factory to find out what kind of weapon the Federation is building.
The player takes the role of Logan Walker. He and Merrick silently take down two guards before moving to the factory. Before regrouping with Keegan, Hesh, and Kick, Logan takes down another guard. Kick leaves the team to obtain a vehicle for exfil. They then move into the factory, shortly after taking down several guards. Logan can follow either Hesh, Keegan, or Merrick through three routes that all lead to blast-doors. Each route involves silently killing guards. Once Kick opens the doors, they enter what is called "The Black Zone" on the other side. Their cover is immediately blown, and they neutralize several guards. Later, they discover what looks like space-based weaponry. When Logan and Hesh take a video of it and scan it, they find out that the Federation is building a kinetic-rod delivery system, based on the design of ODIN (Orbital Defense Initiative). The rods are smaller, but there's more of them. After obtaining the information, Elias orders an airstrike on the entire complex, and the team begins to hack a computer for more information. But before the hacking can be completed, the team is ambushed by a large enemy patrol. They use smoke grenades to blind them and take down most of them with the help thermal-imaging goggles. But the goggles are fried by flashbangs and they are forced to remove them. Fortunately the smoke clears and the Ghosts neutralize the soldiers. They fight their way to a parking lot, where Kick rescues them. As the Ghosts escape the factory, it becomes leveled by the airstrike Elias ordered.
