Tom Clancy's Ghost Recon series of games
Tom Clancy's Ghost Recon is a series of shooters with tactical elements in one of the universes created by writer Tom Clancy. They are all first-person shooter games that follow a squad called the "Ghosts" as they complete different missions and find themselves in different stories.
The series is still being replenished with new games from Ubisoft, in which the “Ghosts” find themselves in completely new stories. The franchise also has story branches - Tom Clancy's H.A.W.X (which includes two parts), as well as Tom Clancy's EndWar.
