Quick Links
At this point inLuigi’s Mansion 2 HD, you’ve gone through a lot of ghosts, picked upgems, capturedBoosand had to endure a never-ending staircase. You know the saying ‘time heals all wounds’? Well, this next boss battle will bring some enemies that are sure to make moving forward seem impossible. InC-Boss: Showtime, you’ll have to face off against theOverset Possessor(Belfry Clock), which will hand over a bunch of enemies in a time-based challenge. Here is what you need to know about this all-time boss battle.
Professor E. Gadd has assigned you to go put the missing pieces of theClock Towerback together in order to get theDark Moon fragment. Before you go over toOld Clockworksagain, he shows us a picture of what was going on behind theClock Tower Gate, in which we see anotherPossessorwith the fragment inside of it. The ghosts are heading over to the top of the tower, which means that we are going to make an entrance there. Also, Mario has been kidnapped!

Clock Tower Gate/Movements
Once you’ve been transported toClock Tower Gate, make your way over to the clock in the back of the room, right in the middle. After you’ve put the hands back onto the clock, you’ll have to use thePoltergust 5000to change the time. To solve this puzzle, go to the right of the room and peek into the crack in the wall, which will show a clock with7:30on it in the bottom right corner. For a bigger reference, there are three gears with a 7, a 3 and a 0 on them. Blow the wheel until the small hand is a little past 7 and the bigger hand is pointing down. The clock will rise, and you’ll be able to enterMovements.
Luigi’s Mansion 2 HD: All Old Clockworks Gem Locations
Here is where to find all the Old Clockworks Gems in Luigi’s Mansion 2 HD.
On your ascent, find the smaller gears to blow on, since those are the ones that’ll bring you up to your destination. Once you’ve reached the door, you’ll enterBelfry, which is a room you’ll not get too familiar with once you get to the ladder. Let’s just say that the climb to the top didn’t require you to climb at all! During the cutscene, you’ll meet theOverset Possessor, which will take control over the clock underneath you.

You will go through a time trial where you’ll face one or more opponents every hour of the clock. You must finish each challengebefore the minute hand strikes 12 o’clock, which will reset the enemies from the same challenge. If you are running behind,you’re able to use the Poltergust to blow the hands back to get more time on your hands. When the clock reaches4, 8 and 12, you’ll face thePossessor, so make sure to dodge their charges and vacuum them when they’re unconscious.The trail is composed of 12 trials, all of which you must pass in order to gain the Dark Moon fragment. Here are the hourly trails:
All Hourly Trials
As you can see, the level of difficulty increases as the trials move on,so keep track of your health and be aware of your surroundings. For theSneakers,look at the sand to track their movements. For theGreenies with the Weapons and Shields,dodge their attacks and flash them when they are visible and reload from their attack.
Exploding Robotscan be easy to trigger but hard to run away from,so try and flash them all at once, if possible, and get around the hand so that it makes it harder for the robots to make it over to you. The last one combines all the enemies you’ve faced,so dodge whenever necessary and don’t be afraid to let go of ghosts if you’re having trouble controlling them. Whittle them down and vacuum them up when the opportunity comes your way.

As you reach the final hour and have defeated the enemies, you’ll once again face off against theOverset Possessor. Again,dodge its charges, which are more frequent than the other boss battles, and when it gets stunned, flash your Stroboscope at it and vacuum it up. For your efforts, you’ll be rewarded with theDark Moon fragmentand will be able to move onto the next location:Secret Mine.
