Dreamchipper is a blast from the past, an adventure for the original version of Shadowrun. It is still a fun read and a fun adventure but a few additional pages with suggestions on ways to update and adapt it to the current edition and setting would not have been amiss.
Dreamchipper for Shadowrun written by James D. Long and published by Catalyst Game Labs (and originally published by FASA in 1989). It is an 84-page PDF which reproduces the original FASA module.
