"War Games" was a Federation mission in the game Star Trek Online. It used to be the third mission of the "Cardassian Struggle" episode, but was removed from the game when the arc was revamped for Season Eleven: New Dawn on 27 October 2015.
Starfleet has scheduled a starship battle simulation, using simulated weapons. However, during the simulation, the USS Athens began to attack the other ships using real weapons and destroyed one of them. The remaining ship reactivates its main weapons and disables the Athens, then boards the ship. There, they discover that the ship's entire crew has been replaced by Undine agents. The leader of the Undine is the one who replaced Captain T'Vala, who confronts the away team on the Athens' bridge. He is defeated, but escapes the ship.
