Outsiders / Checkmate: Checkout

In this 2008 one-shot from DC, Greg Rucka and Judd Winick team up to merge two of the publisher's clandestine teams—the Outsiders and Checkmate—for a single-issue crossover. With art by Joe Bennett, the story pits covert operatives against each other in a tense encounter that tests their loyalties and methods. It's a concise snapshot of the post-Infinite Crisis DC Universe, where espionage and metahuman politics collide.
