Lurking behind the thin vale of sanity, ancient beings of imaginable power lurk, forever ready to bring the world to its knees. These godlike beings from beyond time and space can warp the mind, break the will, and obliterate the body. Now, as they stand against each other, the world will be plunged into a maelstrom of horror and madness. Will your hand guide the victors - or will your eternal legacy be wiped out by a being more cunning, more ruthless, and more malevolent than you? Welcome to a world of unspeakable horror inspired by the works of Howard Phillips Lovecraft, and the Call of Cthulhu roleplaying game, where beings older than time itself manifest on Earth and fight each other, as they prepare to dominate our world. During the game, you will take on the role of an alliance of two nightmarish creatures from the Cthulhu mythos. Your cards will generate Horror that will allow you to power especially formidable abilities and effects, including summoning your Avatars to the field of battle. At the beginning of your turn you rotate the Power Cores on the Character cards and other cards in play area, dealing damage to the opponent, gaining defense and raising horror - a special resource used for powerful actions. Then you can play up to two actions, chosen from: rotating a chosen Power Core again, playing a card (ally, ability, item or maneuver), drawing a card or sometimes summoning an Avatar. At the end there is an obligatory card draw. You win if you deal enough damage to the opponent's Characters or if your opponent has to draw a card from an empty deck. -description from publisher
