Dirge of Cerberus Lost Episode -Final Fantasy VII- is a fully-voiced mobile phone game and is a midquel to the original Dirge of Cerberus -Final Fantasy VII- third-person shooter game for the PlayStation 2. It is part of the Compilation of Final Fantasy VII. Upon its initial release, it featured only a single-player mode, but Multiplayer became available later on.
Lost Episode reveals a missing chapter from the sequel to the 1997 Sony PlayStation video game Final Fantasy VII, Dirge of Cerberus -Final Fantasy VII-. Taking place during the events of Dirge of Cerberus, it involves the adventures of Vincent Valentine struggling to save the world from Deepground, a mysterious army of superhuman soldiers.
Vincent learns that the Deepground soldiers are searching for him in the hopes of harvesting the Protomateria from his body. He decides to investigate the Shinra Mansion in an effort to uncover the truth about his own past — and the mystery behind the Protomateria as well. Reeve Tuesti's goal is to find information on Deepground written by Dr. Lucrecia Crescent. On his way to the mansion, Vincent's chopper is attacked by the Deepground. He survives and makes his way to the Shinra Mansion. The game's story consists of what happened en route to the mansion, events that were previously unknown to players of Dirge of Cerberus.
