High Wires

The High Wires is an outdoor area of the Secret Mine in the game Luigi's Mansion: Dark Moon. The High Wires is accessed by taking the northwest door inside of the Terminal. The High Wires are two sets of zip-lines that connect the Terminal to the Workshop Landing. The Gondola was presumably connected to this system, but has been out of the use. Between the two zip-lines, there is a small platform with a tree and a nest of crows. The door on the south leads back to the Terminal while the door to the north leads to the Workshop Landing.

During D-3: Across the Chasm, Luigi needs to cross the High Wires after melting the ice from the zip-lines via the machine in the Gondola. There is also a treasure chest with coins, bills, and Gold Bars at the end of the second zip-line. During D-Bonus: Severe Infestation, the High Wires might be one of the rooms infested with ghosts.

Starting on B-2: Hit Rock Bottom and most mission after, Luigi can use the first set of zip-lines to reach the platform with the crows' nest. After defeating the crows, Luigi can use the Poltergust 5000 to vacuum the sapphire inside of the nest.

Only during B-3: Across the Chasm, Luigi can melt the ice on the tree using the Gondola's machine. This tree falls over and creates a bridge to an outhouse. Taking the outhouse transports Luigi to a Mini Dimension where he has to hit three Hiders with snowballs. If Luigi successfully completes the task within the time limit, a Treasure Chest with a sapphire appears.

Trivia

 * After Luigi crosses the second set of wires, King Boo can be seen in the background. This is one of the three times King Boo appears in the Secret Mine.
