The dictionary defines the term "complex" as "consisting of interconnected or interwoven parts" and "composed of two or more units". Complex, the Minecraft map, is intended to be a single player adventure that sets the player in the midst of a large multi-dimensional maze, rooms are connected together from each of the four walls, as well as above and below. The player starts with intentionally very little direction. The game adjusts the settings as the player advances. The player must navigate throughout the Complex, room by room in search of the Answer.
