Chapter 1: The Prison

After selecting New Game and watching the opening sequence, you awaken on a trunk in The Maw.

Move right down the dark corridor, holding the run button, and ignite your lighter to see.

Continue right until you hit a dead end with a lantern; approach it to illuminate the area and make progress on the "Light Up Your Life" trophy/achievement.

To the right of the lantern, grab onto the hatch by holding the interact button and move away to open it.

Hold the crawl button to crawl through the vent.

After exiting the vent, follow the path right up a staircase to a small alcove with Statue [01/10]; pick it up and then press the throw button to break it.

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

Climb on the box next to the bed to reach the mattress.

Jump up and down on the mattress multiple times to unlock the Trophy/Achievement: Highly Sprung.

Jump toward the opening on the right and hold the grab button to grab onto the ledge and pull yourself up.

In the next room, grab onto the chair beneath the hung man and push or pull it to the doorway.

Climb up the chair and use it to grab onto the doorknob.

Follow the dark corridor right until you come across a fridge; open it, which will cause a little guy to run right.

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

Backtrack through the passage to the fridge and climb up the shelves to a new level.

Run right while avoiding slugs and jump across the 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 on the other side.

Grab onto one of the boards to the right and pull it off to continue.

As you head into the next room, the floor will collapse beneath your feet, dropping you into a tar-like substance.

Quickly make your way right while avoiding the slugs to push down the wooden door.

Jump across the gap and light the lantern nearby.

Climb up 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.

Follow the walkway the long way around until you reach a lever; rotate it to open a nearby doorway.

Let go and hop across the gap to pass beneath the door before it closes.

On the other side of the doorway, open the hatch on the back wall to release a Nome.

Follow the Nome 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.

Close the door to spot 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, take cover (press the cover button to crouch behind walls or objects) behind the pillar and boxes to the left of the children turned to stone.

Avoid the gaze of the large eye as you cross to the other side of the room to avoid being turned to stone yourself. Run to the back of the room, near the cell doors, and 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 up 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 a Nome [02/13].

Return to the previous room and drop to the floor.

Climb the boxes again to the second floor.

Head left over the eye and enter an open cell on the other side of the area 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 to the left.

Once it's clear, head right into a closet and climb the mesh boxes.

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 multiple times, and grab and eat the food that 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 on the other side.

Climb the box near the doorway.

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

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