Nightmarium is a fast-playing card game for 2 to 5 players, where players create nightmarish "Night Terrors" and vanquish opponents’ monsters by using their powers. Players combine cards representing body parts to complete surreal creatures and trigger their spine-chilling powers. A complete creature is made up of three parts: legs, a torso, and a head. Most cards have a special ability that is activated when the player completes the creature.
The new edition will include the expansion “Legions of Horrors”, featuring a new type of cards that can be played on top of a completed creature to make them become “incarnated”- allowing them to activate some abilities a second time, while becoming immune to all abilities until the end of the game.
