Phantoms are a group which are striking against the Ghosts in secret before disappearing. They killed Allen and Bob, but a third Ghost escaped. They are the team's deadliest enemies and are formed from ex-Ghosts and other individuals who are seeking their own agenda.
The Phantoms were added to the free-to-play multiplayer shooter Ghost Recon Online as part of the Phantom Pack upgrade on July 10, 2013. Players may receive rewards from the Phantom mission by acquiring up to 100 million points.
As part of the official release, the Phantoms are part of the "narrative layer". According to the game's producer Corey Facteau, they were envisioned as being "gray characters" to better reflect today's reality. They are also seen as two-parts of the same coin with the Ghosts.
