How to install:

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

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 clinical_trial_blutsauger_skin/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_clinical_trial (blu and red), c_ctrial_glass and weapon glow red_/blu" and the other .vtf and .vmts into steam/steamapps/%yoursteamname%/team fortress 2/tf/materials/models/weapons/c_items.
