Conspiracies is the first installment in the Conspiracies series of full motion video adventure games. Conspiracies was developed by Anima Interactive.
The game is set in the 21st century, where the human population suffers from a number of problems, including overpopulation, poverty, organized crime, and depression. Earth has dissolved into a federation of cities. The game is specifically set in Greece, where each city-state has its own governor and local government. However, this is overshadowed by a coalition of political lobbies, the big companies, the organized crime, that imposes their own reality.
Nick Delios, the protagonist, was originally in the academic world, but left it after being kicked out of his team. He eventually becomes a detective, specializing in cases of industrial espionage. When Thanos Pekas, Police Inspector and an old friend, asks him unofficially to help him solve a murder case of a small time crook, Delios accepts. He soon learns that the case is far more complex than he thought, involving multiple conspiracies.
