Citi-Block

Citi-Block is a supplement published by Games Workshop in 1987 for the near-future dystopian science fiction role-playing game "".
Publication history.
"Citi-Block" was written by Richard Halliwell, Carl Sargent, Alan Merrett, and Graeme Davis, with art by Gordon Moore and Dave Andrews, and was published by Games Workshop in 1987 as a boxed set with a 20-page booklet and 12 color cardstock sheets (four pages of cut-out props and eight 11" x 16" floor plans.)
Contents.
"Citi-Block" contains full-color building floor plans marked in 25mm/1-inch squares, with detailed rules for designing standard Mega-City blocks, as well as rules for use with "Warhammer 40,000". The floor plans include eight 11” x 17” layouts printed in full color on thin cardstock: 
Also included are two 11” x 17” sheets of thicker card stock, printed with various cut-out details like desks, cars, plants, and phone booths.
Reception.
In the July 1989 edition of "Dragon" (Issue #135), Ken Rolston called the floor plans "perfectly designed for role-playing displays." He liked the suggestion of "a worn, shabby future" and suggested they could be used for games outside of "Judge Dredd", although their less-than-pristine look made them "less useful for far-future settings like the or s, unless used for scenarios on backwater or frontier planets." He called the charts and guidelines for creating a Mega-City block in the rulebook "admirably detailed and specific, and are an essential supplement for anyone running a "Judge Dredd" game campaign." Rolston concluded, "As floor plans for role-playing displays, the Citi-Block pack is good-looking, utilitarian, flexible, and suitable for many near-future SFRPGs."
