Throughout the game, the rig has been a distant landmark and an obvious end-goal, but when the Player finally gets to enter they are transported to an alternate dimension where the rules of physics no longer apply. This is the crystal realm and the rig is shattered into mind bending yet unexpectedly traversable pieces making for an imposing and memorable arena in the climactic showdown with Wilson.
Although our original final level was supposed to take place on the deck of a ship in the docks, the rig seemed a much more interesting choice. Its shape naturally gives the feeling of an evil fairytale castle. As a combat arena, it was important that the detail, lighting, and geometry didn't become so overwhelming that they interfered with gameplay. This was tricky, as so many elements are in play. Despite the vibrant hues, we kept actual colours to a minimum so that walls, floors, interaction points etc were easily read even in the midst of the fighting.
