Find the floating door document
Inside Prison, you’ll find a secret document with the image of floating doors. This is a white piece of paper that can spawn randomly inside the building, but we’ll guide you through the path you can use to check all the areas.
Starting from the bottom where you enter, check around the walls with the pipes, as the document could spawn here. If not, proceed upwards into the “showers gulag” portion of Prison. The image you’re looking for could also spawn around the walls by the shower lockers.
Carry on, moving inside the circular area with the prison cells. Search each prison cell that you can enter. Then, head upstairs and search the next level of cells. From this level, you can take the double doors that lead into the smaller prison cells above the shower gulag. The document can also spawn in one of these cells.
