Psst! Be careful — whatever you do, don't turn around. It could be right behind you, looking over your shoulder, gazing in amazement at this box that seems to have come to you from the very depths of the world of dreams. A game about building nightmares so terrifying you'll see half of them in your dreams. You have cards representing Night Terrors, and the more of them you combine in the right order, the more monsters come to life, and the more horrifying they become. Create monsters that will make your opponents gasp in horror. Nourish them with your own fear. Make them stronger. Only then will you achieve victory and become the Master of Terror. Includes the Legions of Horrors expansion. Nightmarium is a fast–playing card game for 2 to 5 players. Take it along to your next gaming night or family trip, and have fun creating nightmarish creatures, and vanquishing your opponents’ monsters!
