How to install:

All:
Extract the .zip and open the folder marked perscription_package_blutsauger.

Then either:

1, Copy the tf folder into your steam/steamapps/%yoursteamname%/team fortress 2/ folder,  your computer should then ask you if you want to merge the two "tf" folders together, ok it. You have now installed the weapon fully.

This may not work on some computers so if that includes you:

YOU MUST:
go into the perscription_package_blutsauger/tf folder again and go into models/weapons/, you should see a folder called c_models, copy EVERYTHING from them into the c_leechgun folder in your steam/steamapps/%yoursteamname%/team fortress 2/tf/.



Then go into clinical_trial_blutsauger_skin/tf/materials/models/weapons/c_items and copy both the "c_mag_neelder (blu and red), and c_mag_needler_glass.

To get the backpack icons working repeat the process for their respective folders.
