From the introduction: This is the eighth sourcebook for Macross 2050. This book repeats the elements from Macross, Southern Cross, Mospeada and Megazone 23 as they were presented by Harmony Gold as Robotech. Names and information will be shown as it was in the Robotech story, with any other needed parts invented. This book will not cover Robotech III (Orguss) or Robotech 3000 since neither animation went into production. However it does cover what Sentinels information is available, as well as the new Shadow Chronicles material. ... This sourcebook will not include adventure information from the Robotech RPG by Palladium books, which can be converted with minimal difficulty[.]
