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 card from their deck made of 3 clans. Those clans are drafted at the start of the game, and the 2 unchosen one change the game rules ! A game is played in 3 rounds maximum.

Each round, you will:

- Add cards to your Army (Troops, Heroes and Immortals) and trigger their effects.

- Engage in a Great Battle. The player with the strongest Army wins a Supremacy Token.

- Honor the Song for the Dead. Each player sacrifices half his army.

There are several ways to win: get 2 Supremacy Tokens OR unlock 5 Activation Tokens OR have 15 face-up cards in your Army OR reach an alternate victory condition (Goan-Sul or Justice).
