Risk Godstorm is a Risk variant board game published by Avalon Hill and designed by Mike Selinker with developers Richard Baker and Michael Donais. The cultures of the Celts, Norse, Greeks, Egyptians, and Babylonians clash for supremacy of the ancient world. Players invade territories, play miracle cards, sink Atlantis, and conquer the underworld. The latter is a significant addition to the Risk series, as soldiers do not leave the game when they are killed, but instead go to their heavens and then embark to take over the underworld.
Each player has a pantheon of four gods to bring onto the ancient world map, to whom the game ascribes the spheres of the Sky, War, Death and Magic. Gods can only exist on the main map; they cannot exist in the heaven or the Underworld. Respectively, these are:
- Marduk, Gilgamesh, Druaga and Ishtar for the Babylonians.
- Lugh, Nuada, Arawn and Brigid for the Celts.
- Ra, Set, Osiris and Isis for the Egyptians.
- Zeus, Ares, Hades and Hecate for the Greeks.
- Odin, Thor, Loki and Freya for the Norse.
A God of the Sky will add an additional die to its players roll when it competes in a Godswar. If a player destroys one or more gods during his or her turn, then he or she may draw a miracle card from the sky deck. Sky cards are defensive cards that are activated on other players' turns.
If the attacking army possesses the God of War, then the attacker will win ties. If a player conquers three (3) or more territories during his or her turn and they have a God of War on the map, then he or she can draw a miracle card from the war deck. War cards are cheap offensive cards that are used on that player's turn.
Normally, when a battalion is killed in battle, it will travel to its respective heaven and then progress into the Underworld. However, if the attacking army possesses a God of Death, all troops killed are placed back in their respective player's pool. If a player controls a crypt in the Underworld at the end of their turn, then he or she can draw a miracle card from the death deck. Death cards are expensive to activate, but for the most part have devastating effects.
Having a Goddess of Magic in his or her army allows a player to re-roll ones --whether they are attacking or defending. If a player rolls three of the same number and has a God of Magic under their control, they can draw a miracle card from the magic deck. These cards are also known as 'relics'. Relics are played as soon as they are drawn and stay in play until they are destroyed by another cards effect.
