Papers Tools

Unpacking sharedassets0.assets:

./papers-tools -g /path/to/steamapps/common/PapersPlease unpack

You can also pass the Art.dat file as the input directly.

Patching

To overwrite textures, just add the new texture in the same path as the original one in your patch directory. For example, to replace the RifleTranq.png texture, put the new texture in patch/assets/textures/RifleTranq.png.

Editing xml files is also supported. The tool will merge your changes with the original game xml files. Example for adding a new paper (patch/assets/data/Papers.xml):

<?xml version="1.0" encoding="UTF-8" ?>
<papers>
    <paper id="ExamplePaper" outer="ExamplePaperOuter.png" reveal="fromslot" oddshape="true">
        <page image="ExamplePaperInner.png"/>
    </paper>
</papers>

To override entire sections that don't have an id or attributes, add id="override" to the base element:

<?xml version="1.0" encoding="UTF-8" ?>
<facts>
    <nations id="override">
        <nation name="Thalvoria" cities="Ebonvale;Aerofell;Silvanwood" citizen="Thalvorian"/>
        <nation name="Vectis" cities="Nexaria;Azurea;Agrona" citizen="Vectisan"/>
    </nations>
</facts>

for more information on the format, just check out the unpacked files.

You can even replace audio files, but a separate json file is needed to map the original audio asset object to the new one.
Example (json path: patch/audio_patches.json audio path: patch/audio/awp.fsb):

[
  {
    "objectName": "border-gunshot",
    "patchedPath": "audio/awp.fsb",
    "loadType": 0,
    "channels": 2,
    "frequency": 48000,
    "bitsPerSample": 16,
    "length": 4.642667,
    "isTrackerFormat": false,
    "subsoundIndex": 0,
    "preloadAudioData": false,
    "loadInBackground": false,
    "legacy3d": true,
    "compressionFormat": "adpcm"
  }
]

The audio files need to be unity compatible fmod sound banks. Any other format will not work.

To apply the patch, run:

./papers-tools -g /path/to/steamapps/common/PapersPlease patch -p /path/to/patch

-p /path/to/patch can be omitted if the patch is in the default path ./patch.

Reverting

To revert the changes made by the patch, run:

./papers-tools -g /path/to/steamapps/common/PapersPlease revert

For less common used commands, check the built-in help:
