From publisher blurb: This fourth set of cards designed for use with the Mutant Future game created by Goblinoid Games, though easily adaptable to other OCR type game systems for sci-fi or sci-fantasy type settings. The Print and Play PDF consists of four face sheets, four backing sheets (alternating) with the face sheets consisting of six cards each. Also, the PDF version consists of Adobe layers and a full color version, greyscale version, and black and white version can be generated from the same file.
