Games Workshop have posted a new article discussing the development of the 40K Dark Eldar rules.
From their website:
Phil Kelly is the devious mind lurking behind Codex: Dark Eldar, a self-professed xenos lover whose long-term association with all things Eldar made him the perfect candidate to write the new codex. In November 2010’s issue of White Dwarf we included a comprehensive designers’ notes article, delving into the genesis of the Dark Eldar’s miniatures range, background and even looking at some of the artwork produced for the book. In this article, White Dwarf & Web writer Adam Troke follows on from that feature, talking with Phil Kelly to explore the themes and ideas that Phil used when creating the rules for the Dark Eldar, and their relationship with the miniatures and background.
