Captain Blood

The objective of the game is to track down and disintegrate five clones of Captain Blood. To find them, the player must speak to aliens and gain their trust. Communication with aliens occurs via an icon-based interface known as UPCOM. This consists of around 150 icons, each representing a different concept. As each alien race discovered speaks its own language and reacts differently, the player must learn to negotiate using these UPCOM concepts in a style that suits the races. (wikipedia.org).
