The Jalaanx universe is dominated by 8 Immortals, demigods engaged in conflicts since the dawn of time. Alliances are made and broken every time a new war comes. The red moon approaches, forge a new alliance and be prepared for an epic battle. Even if a military victory is always honorable, especially for the great Goan-Sul, a hidden 9th demigod offers new ways to win the battle...

Gosu X is a combo card game in which players build up their army using the cards from their deck, made of 3 of the 8 clans in the game. The 2 clans unchosen by either player add ongoing rules and effects. At the end of each round, a Great Battle takes place, where the player with the highest military value comes closer to victory.
