Cobra has taken control of Sierra Gordo and Trucial Abysmia, but these countries are just the opening gambits in Cobra Commander's plans. Deep in the jungles of Sierra Muerte, General Colton has evidence that the terrorist organization's plans are more ambitious than anyone would suspect. Can he escape the agents who pursue him long enough to warn General Hawk and the G.I. Joe team? Meanwhile, Snake-Eyes has left the team to embark upon a mission of his own. In the U.S.S.R., Daina embarks on a similar journey across Europe. Their actions will forever change the lives of the men that they pursue. Building on the action of G.I. Joe: First Salvo, G.I. Joe: Honor raises the stakes and expands the roster to include the '83 Joes, General Colton, Kwinn, Shadow Tracker, the Oktober Guard, the Dreadnoks, and more.
