To Install and use this mod follow the following steps

• Find your game on your PC localized files, if you are on steam do this by clicking the cog then Properties then Local Files then Browse.
• Open the "Signalis_Data" Folder
• Open the save folder
• Make sure you do not have a 05 Save Folder, if you do then you need to free this spot. This can be done by either deleting the 05 Folder and losing your profile 5 save, or by deleting another profile save and renaming the 05 folder the number of the deleted save (if profile 3 was deleted then 03) 
• Extract the attached folder into the Signalis_Data/Saves folder, it should extract as a folder named "05" if it does not rename it to 05
• Open your game and load profile 5, this profile will now contain the machete, note you will have to skip the first segment of the game as the save loads you at the very first save point in the game (In ReEducation)
