Palladium Books has announced plans to release Robotech: Expeditionary Force Marines Sourcebook One for its Robotech RPG Tactics RPG/miniatures game in March.
The book was originally solicited as Robotech: UEEF Marines Sourcebook, and was recently updated to include ‘Sourcebook One’ in the title on their website.  "This is the first of two UEEF Marine books," Palladium president Kevin Siembieda confirmed, saying the second volume will also release later in 2014.  
Sourcebook One is written by Irwin Jackson, and has 160 pages.  The book promises new character classes, mecha, aliens, weapons and gear for the Marine Corps of the United Earth Expeditionary Force (UEEF), as well as history, training and organization on the group.  MSRP is set at $20.95.
The book will follow closely on the heels of the updated release of the Robotech RPG Tactics box set (see "'Robotech RPG Tactics' Delayed").
