Killing is Harmless: A Critical Reading of Spec Ops: The Line, an analysis of virtual violence by critic and academic Brendan Keogh, is now available starting at $2.99.

Officially announced on Nov. 3, Killing is Harmless is Keogh's 50,000-word attempt to answer questions about the nature of violence in games, as well as "Western interventionism and wars conducted via proxies." Keogh hones in on Spec Ops: The Line, beginning with the game's opening menu to its final epilogue, and analyzes the game's characters, stages and player decisions. The title comes from one of the game's loading screen lines: "To kill for entertainment is harmless."

The book is available on a pay-what-you-want scale, beginning with the minimum launch price of $2.99. The sale price will last until Dec. 21. You can purchase Killing is Harmless as a PDF and ePub combo at Stolen Projects.
