This mod replaces Chloe and Max by their older selves in the Farewell Episode.
Chloe and Max also both have specific pirate outfits.
Instructions:
Extract the archive into the folder "C:\Program Files (x86)\Steam\SteamApps\common\Life is Strange - Before the Storm\DLC\E4" (or your own path if different)
Run "part1.exe" and follow the instructions (basically click on "next" a few times and "close")
Do the same thing with part2, part3 and part4.exe
You're ready to play
Notes:
Once the mod is working correctly you can delete the four .exe if you want. The installer will also create backup files (with the extension .bak0000) if you wanted to recover your original unmodified files.
The cemetery scene and the one after are pre-rendered so they can't be modified.
