Alone In The Dark - Chapter 4 Blueprint Puzzle Guide

Late into Chapter 4 in Alone in the Dark you will find yourself trapped in the Medical Ward Morgue. In order to escape you will need to assemble blueprint pieces in the correct layout to match the floor plan of the ward, but you aren't provided with any obvious clues. In order to correctly map out the floor plan, you will need to find a hidden clue that isn't labeled as one by the game.

How to solve the Blueprint puzzle

In order to solve the blueprint puzzle, you will need to find two sets of blueprint pieces in crates in the Morgue. These crates are on the various shelves in the small area and are fairly easy to find. With all of those pieces you can begin to assemble the blueprint puzzle. To place the pieces correctly, you need to match them to the floor plan underneath the pieces. Lift a piece up by selecting it and you can see each room and how it's oriented. The correct solution looks like the image above.

The folder goes in the blank space in the top left corner, with the various rooms laid out elsewhere. Once you figure out where each room goes, the quickest way to tell if it's rotated correctly is to get any text to set in a way that you can read it normally. Most pieces have a room name in the top corner, while some have a list of names or other information that you can use to rotate them the correct way.

Once you have placed the pieces in the correct order, a short cutscene will start signaling that you solved the puzzle. Solving this puzzle will give you the Morgue key, which allows you to leave the Morgue and explore the rest of the Medical Ward.
