Once gamers have completed every stage in Old Clockworks mansion, they'll move on to Secret Mine. This mansion only has three missions, but that doesn't mean players will simply breeze through it. Secret Mine is a huge manor with various basement levels and dozens of floors, so it won't be an easy task to find every Boo hidden inside.

Here is how players can get the fire back to the Chalet so they can access the elevator in Luigi's Mansion 2's Secret Mine mansion.

While normally gamers would have to capture a total of five Boos in a mansion, this time around, they will only have to find three Boos - one per mission. For those who are having trouble locating each one of these tricksters, this guide will point them in the right direction.

Once players have found the three Boos inside the mansion, they'll unlock Severe Infestation, Secret Mine's bonus mission. Whenever gamers capture all the Boos in a mansion, they'll gain access to a bonus mission. These levels are crucial for players who want to obtain the three Professor E. Gadd Medals; the requirement to get one of the medals is to get a 3-Star ranking on all the missions in the game, and this includes bonus missions.
