Chapter 1: The Prison

After gaining control, move right down the dark corridor, holding the run button, and ignite your lighter to see.

Head right to a dead end with a lantern; approach it to illuminate the area and progress the "Light Up Your Life" trophy/achievement.

To the right of the lantern, grab onto the hatch, move away to open it, then hold the crawl button to enter the vent.

Exit the vent and follow the path right up a staircase to a small alcove containing Statue [01/10]; pick it up and press the throw button to break it.

Continue right and crawl under the boarded-up doorway into a bedroom.

Climb on the box next to the bed to reach the mattress; jump up and down multiple times to unlock the Trophy/Achievement: Highly Sprung.

Jump toward the opening on the right and grab the ledge, then pull yourself up.

In the next room, grab the chair beneath the hung man, push or pull it to the doorway, climb up, and use it to reach the doorknob.

Follow the dark corridor right until you find a fridge; open it to make a little guy run right.

Continue right and crawl through the small passage to find another lantern next to Nome [01/13]. To unlock the "Little Lost Things" trophy/achievement, find all 13 Nomes and hug them by approaching and pressing the interact button.

Backtrack through the passage to the fridge, climb the shelves to a new level, and run right, avoiding slugs and jumping across gaps.

In the next room, pull the lever above the box to open the door on the right.

Jump across the gap and enter the room; grab onto one of the boards on the right and pull it off to continue.

As you enter the next room, the floor will collapse; quickly make your way right while avoiding slugs to push down the wooden door.

Jump across the gap, light the nearby lantern, and climb the wooden planks on the right to reach the next level.

Carefully cross the beam on the left, head up some stairs, and follow the wooden walkway toward the screen until it ends.

Jump right and continue up more stairs, then follow the walkway the long way around to a lever.

Rotate the lever to open a nearby doorway, then hop across the gap to pass beneath the door before it closes.

On the other side, open the hatch on the back wall to release a Nome and follow it through a hole on the right wall.

Climb the makeshift rope on the right to continue.

After dropping into a bathroom, light the lantern in the corner.

Push open the door to the rest of the bathroom area, then close the door to reveal a lever.

Pull the box of toilet paper beneath the lever to reach it, cutting power to the area.

Squeeze through the bars on the right into a playroom; keep running right and squeeze through another set of bars before the power returns, electrifying the bars.

Continue right past a number of prison cells.

In the next room with more prison cells and a large eye, take cover (press the cover button to crouch behind walls or objects) behind the pillar and boxes to the left of the petrified children. Avoid the gaze of the eye as you cross to the other side of the room to avoid being turned to stone. Run to the back of the room near the cell doors, cross to the right, then run forward and right when the eye is looking away.

After passing the eye, climb atop the single metal box and light the lantern to your left.

Climb the metal mesh to the upper floor.

Follow the stack of boxes to the right and drop off the right side to land on a different stack of boxes.

Crawl through the mesh box on the right wall to find a hidden storage room with another lantern and Nome [02/13].

Return to the previous room, drop to the floor, and climb the boxes again to the second floor.

Head left over the eye and enter an open cell with finger paintings; grab the Statue [02/10] in the front right corner and smash it.

Backtrack to the right and exit the prison ward into a bedroom; hide under the bed on the right and wait for a warden to enter and leave.

Once clear, head right into a closet, climb the mesh boxes, and jump onto the shelves to enter another vent.

After crawling through a vent and dropping into an adjacent room, you will experience uncontrollable hunger. Keep heading right, crouching in pain, then grab and eat the food the NPC (non-player character — anyone the game controls, not you) throws through the bars.

Climb the boxes to the right and crawl through the gap in the metal bars.

Continue right through a shower room to a walkway with electrified bars; climb the box near the doorway.

Follow the path into the background and climb the mesh boxes or jump to the back wall, then climb the mesh boxes on the left.

When you can no longer climb up, press the back jump button.
