Enkidu is a cooperative game designed by Oriol Comas i Coma, and developed by Ibermática, a Spanish enterprise. Enkidu is a historian from the future that travels in a time machine to the past to discover a great secret. To achieve his goal, he must decode the clues hidden in Sumerian clay tiles marked with cuneiform signs. During the game the players are characters from around the hero, and they will try to get new tiles to discover the enigma hidden in the tile. To fulfill their challenge they must compete, but also collaborate, helping each other and negotiating, as well as to take on risks and make decisions. The game has two phases: the initiation phase to the secrets of the Sumerian Gods, and the phase of the full development of the technologies that will appear in the future.
