How to unlock the Weight of the Beast achievement in The Cave - Definitive Guide
Knight (229 lbs)
Hillbilly (175)
Time Traveller (194)
In the Carnival level (where the scale is) you will find 3 items:
Sledgehammer 15
Wrench 3
Barbell 50
Just have each character carry these items onto the scale and then hit (x)
The Lahaarl makes a great point in the comments below: Be sure to do this BEFORE getting the ticket, otherwise the scale will no longer function!
There will be a scale during the "Carnival" puzzle where a man guesses your weight. Across the level you will find a sledgehammer, a barbell, and wrench. Have your characters hold these items and all stand on the scale at once and press the square button. The man will guess your weight as 666lbs and the trophy will unlock.
The barbell serves no purpose outside of this trophy so feel free to discard it afterwards.
This trophy can only be earned in the Hillybilly’s story.
Firstly, to earn this trophy, you must select the combination of the Hillbilly, Knight and Time-Traveller at the start of the game. Then, once you reach the carnival, you need to find the wrench, sledgehammer and barbell. Equip these 3 items with each of the 3 characters (it doesn’t matter who carries what) and stand on the pressure pad on the “Guess Your Weight Machine”. Press the button with and the attendant will guess your weight as 666. The trophy will subsequently unlock.
Bear in mind that you must attempt this before solving the puzzle and getting the “Carnival Ticket” from the machine, otherwise the attendant will have closed the ride, forcing you to reload the checkpoint.
Required: Hillbilly, Knight and Time Traveler.
Once you're at the carnival you'll need to gather up the Wrench, Sledgehammer and Barbell and - while holding these items - stand on the scales. Do this before solving the scales puzzle as once the puzzle is solved the scales will no longer work. Here is the math for you:
Hillbilly - 175lbs
Knight - 229 lbs
Time Traveler - 194lbs
Sledge Hammer - 15lbs
Wrench - 3lbs
Barbell - 50lbs
Total - 666lbs!
