The Old Ones have risen. Monsters walk the Earth. Humanity is finished, but the struggle continues. Which Great Old One will rule the ruins of Earth? Now, you take charge! Cthulhu Wars Duel: Extinction is a fast-moving two-player strategy game in which you play as The Sleeper, primordial god of slumber and hunger or Ithaqua, the Windwalker, god of outer space and all that is coldest and darkest. Each side is strikingly different with unique units, abilities, and strategies available. Cthulhu Wars Duel: Extinction is fully compatible with the original Cthulhu Wars Duel game. Both are standalone products, but Factions and Maps can be mixed and matched in any combination! —description from the publisher
