Trivia

 * Along the north borders of the map the player can hear loud and ominous rumbling noises; likely detailing movements of the shear amounts of ice.
 * There is a small waterfall emerging from a hole in the western ice wall. If the player crouches in the hole, a bugged repeating coughing sound will be heard from the player's character.
