From the Back Cover of the Core Rulebook:
A menace so deadly that Fleet has quarantined their star system. Are they a super-human menace or a new stage of human evolution?
Final Sword Productions brings you Psibertroopers, a book where giant mecha, psionics and space opera intersect. Welcome to Ceybrodin, a star system inhabited by a Diaspora group known as the Psibers. Using the classic D6 system (previously used by WEG in the Star Wars and Metabarons RPGs), this first book in the Dead Night of Space series introduces you to a world where powerful Psibers pilot giant mecha and can use their powers to jump through solid objects. The book gives you quick start rules for those who do not have a prior D6 space opera rulebook, plus the source material necessary to add this star system to any D6 space opera campaign. Also included is background data for campaigning in the Dead Night of Space universe. In addition there are new variant rules for Psi powers and 'Chesspiece Goons' (quick creation and use NPCs).
