From the introduction:
ESP & Eyeliner is a supplement made for use with The Black Hack, inspired by that ever-enduring combination of extra-sensory powers, otherworldly horror and the 1980s.
Lurking at the edge of society are individuals with mental powers beyond the scope of the average mind. They are our only hope for fighting back the darkness that exists beyond the curtain.
Rules from The Black Hack apply normally unless otherwise noted.
