In this 2-player deck-building game that utilizes Cryptozoic's popular Cerberus Engine, players compete head to head using direct "confrontations" to take down their opponent's oversized character cards.

Players take on the roles of Green Lantern and Sinestro. Each oversized character card has a cost of 9, 12, or 15 and has a unique ability. As they are defeated, the characters grow in difficulty to take down, and their abilities also improve. Players start off on an even playing field with identical decks of cards. They then use the cards in their hands and special abilities to buy bigger and better cards. As the game progresses, each player's deck becomes unique, strengthened by his or her decisions. Players attack and defend until Green Lantern or Sinestro stands supreme over his iconic rival!
