The first Orb will be hiding in the pond that you jump into to escape the dogs. Dive down and to the left to find a cave. Inside is the first hidden Orb. To reach it, simply tip the large wooden beam over.

Breaking this Orb unlocks the ‘Murky Waters’ achievement.

Somewhere in the middle of the cornfield is an extremely well-hidden trap door. The easiest way to find it is to hold the grab button while running; you’ll stop when you grab onto the trap door. Climb down and enter the room on the left to find the second hidden Orb.

Breaking this Orb unlocks the ‘Field Research’ achievement.

After the chick-shooting puzzle, you’ll jump into a cart of pigs. Grab the cart and push it against the wall on your left. Standing on the cart, pull at the barn wall to break a board off and allow entrance. Step inside, climb the rope and jump to the left to find the third hidden Orb.

Breaking this Orb unlocks the ‘Wee Wee Wee’ achievement.

After pushing over a safe and breaking a hole in the floor, drop into the hole. On the left wall is a grate you can pull off. This leads to the fourth hidden Orb.

Breaking this Orb unlocks the ‘Left Behind’ achievement.

When you are sliding down a rooftop and have to jump and grab a pipe on the opposing wall. Once you do that, climb down a little and jump back across to grab the ladder. That leads down to the fifth hidden Orb.

Breaking this Orb unlocks the ‘Obscure Foundations’ achievement.

Note:

This is the first of three Orb locations where a musical pattern can be heard. A repeating set of orchestral string notes plays on repeat. While it doesn’t matter yet, it plays an important role in the game's alternate ending. The note pattern is as follows.

Low - Mid - Mid - Mid - High - High - Low - Mid - Low - Low - Low - High - High - High

Progress through the game until you enter the submarine, then progress until you find yourself in a submerged stairwell between red doors. Descend to the bottom and slam into the box to uncover a path to the sixth hidden Orb. You’ll need to solve the puzzle to break this one.

Puzzle Solution: Using the left helmet, move dummy man Alpha into the water and on top of the submarine. Disconnect and enter the sub yourself. Use the sub’s boost to launch dummy man Alpha into the rightmost helmet. Return to the left helmet to daisy-chain control dummy man Beta into breaking the Orb.

Breaking this Orb unlocks the ‘Friends In Low Places’ achievement.

After the first proper encounter with the long-haired water person, you’ll be in a massive pool. Go all the way to the left until you find a wall. Boost the sub up and into the wall to break debris down. Climb the debris to find the hidden seventh Orb.

Breaking this Orb unlocks the ‘A Tableau’ achievement.

During a segment where you have to collect about 20 dummy men to progress, you’ll eventually ride on a massive rail cart that leads to a sandy area with a wooden plank wall. Gather the dummy men past it and return, using them to help pull a plank off of the plank wall. This will lead to a cave system. Grab the torch off of the wall, you’ll see why soon enough. Navigate the challenge to find the eighth hidden Orb.

Breaking this Orb unlocks the ‘Pack Mentality’ achievement.

After an extended escape from the long-haired water person, you’ll come across a section with a button-operated door. Lure Long-Hair over to the right side, then jump into the left side and swim to the left underwater. This will reveal a small vent tunnel where the ninth hidden Orb is. Push the grate to the left if you want to avoid dying by Long-Hair when leaving.

Breaking this Orb unlocks the ‘Respite’ achievement.

Once you can breathe underwater, proceed through the office building as normal until you reach an automatic aperture. Locate the large door with red handles down and to the left. Pull down on the handle in the middle and then pull on a smaller handle at the top of the door. Doing so will open a path leading to the hidden tenth Orb.

Breaking this Orb unlocks the ‘Unfathomable’ achievement.

There is a segment where you have to rotate a platform to cover yourself from a wire-shooting light. Stop when the platform is at its highest and backtrack to the flooded room just prior. Find the small section that you can fully submerge yourself in and swim down into it. This will lead to the hidden 11th Orb, which should be in a reachable position.

Breaking this Orb unlocks the ‘Clockwork’ achievement.

Progress to the room where you encounter antigravity water for the first time. Once you have a second jumping box, push it to the right where a red button is hiding in the air above you. Using the box, press the button to reveal a platform. Press it again to send the platform back up, being sure to jump onto it as it rises. This leads to the room with the twelfth hidden Orb.

Breaking this Orb unlocks the ‘Room For Reflection’ achievement.

Note:

The musical notes heard by Orb five can also be heard in this room.

Progress until you have a collection of lumpy dummy men and have to work an elevator. Separate your dummy men into two groups by rushing into and using the elevator. Ride it back up and look to the right for a dangling yellow cable. Have your nearby men toss you up to grab it and climb. You’ll regroup with your other dummy group, which you can guide down the hall to the 13th hidden Orb. Have them toss you up to grab the Orb to break it.

Breaking this Orb unlocks the ‘Office Space’ achievement.

Note:

The musical notes heard by Orb five and 12 can also be heard in this room.

After the area with scientists viewing something in a large pool, you’ll encounter a ladder that leads down to an elevator. Climb it up instead to discover the location of a massive Orb in a grassy field. This is the 14th and final Orb. The door on the Orb will only be open if you successfully break the 13 other Orbs first. If you already did, step inside and break it from inside. It’s not seen on camera, so just walk all the way to the right, grab, and pull left until something happens.

Breaking this Orb unlocks the ‘The Last One’ achievement.
