The New Frontiersman features articles from the original series's characters Hector Godfrey, Seymour Smith and Doug Roth.
It has been released in physical format at Chicago's C2E2 convention and online at newfrontiersman.net.
The digital version includes highlighted words that link to supplementary material including previews and an Instagram-style shot of Rorschach.
The New Frontiersman publication originally appeared in the pages of Alan Moore and Dave Gibbons's 1986 miniseries.
DC has promised further viral releases for the controversial prequel miniseries.
Darwyn Cooke, who is writing and drawing the Minutemen title and penning the Silk Spectre series, recently revealed that he originally turned down the project.
Moore - well known as a detractor of the project - recently said that he was "less than delighted" about Before Watchmen during an interview with the BBC.
Before Watchmen will debut in June.
