— Brainiac Hairpiece publicity blurb
The Brainiac Hairpiece is a miscellaneous item for the Engineer. It is a set of mutton chops, and features a frizzy white hairpiece and mustache. The item was named the "Maths-Enhancing Hair-Do" in promotional materials on the Australian Christmas 2011 update page on the TF2 Official Website and the Weta Workshop website.
The Brainiac Hairpiece was later contributed to the Steam Workshop, at Valve's request.
