The 5th Edition Player's Guide was very similar to the 4th Edition Player's Guide, varying only in minor corrections, additions, and clarifications. The 5th Edition of the game included the revised Player's Guide, a revised GM Reference, and the Quasar RPG Referee Assistant for MS Windows (EXE). Otherwise, the 5th Edition utilized existing 3rd Edition products without modification.
The guide was released in RTF and DOC format; both are identical except in very minor formatting. The DOC version was released as a self-extracting archive (EXE).
