II – The Koshan Conspiracy is a futuristic point and click adventure game written by Computer's Dream and published by Ubi Soft in 1992.

It is a futuristic role-playing game in which the player explores the city, talks to non-player characters, tries to solve puzzles, travels to new cities by use of a mini-game, buys weapons and ammo, engages in fire fights (also by way of a mini-game), buys a spaceship, and enters space.

The player can even re-wire a wrist computer (B.O.B) in the game to perform different functions.

The Amiga and Atari ST versions shipped with a physical dongle to prevent piracy.

The magazine concluded that it was "an enormous game, offering a richly textured, futuristic gameworld that gamers can find themselves easily drawn into".
