Brain Bucket

The definition of a "Brain Bucket":

It is a helmet that just covers the skull and nothing else. It is the minimum helmet one can wear and still be legally helmeted. Probably not much protection.

How to install:

1) Choose which hat you want to replace. Open the appropriate folder.

2) Drag and drop the "Models" and "Materials" folder into "Steam/SteamApps/Username/Team Fortress 2/tf/".

Note: The GhastlyGibus and BillsHat versions don't include a replacement icon.
