Part of 'Assistant Editor's Month' at Marvel, where the assistants were allowed to print a single issue without editorial interference as the Editors were away at an editor's conference (San Diego Comic Con) that month.
G.I. Joe [Hawk; Snake-Eyes; Scarlett; Gung-Ho; Snow Job; Doc; Clutch; Breaker; Wild Bill; Tripwire; Short-Fuse; Cover Girl; Ace; Zap; Rock 'N Roll]; General Flagg (death); Kwinn (death); Cobra [Cobra Commander; Destro; Baroness; Dr. Venom (death); Major Bludd; Scar-Face (death); Cobra Soldiers]
The Joes learn of Cobra's plan to uncover the Pit's hidden location, and construct a false headquarters over the real thing, while setting them up to believe that their base is under quarantine from Scar-Face's infected body, cured by Doc. Cobra then attacks, and the Joes defend. The battle is won by the Joes but at a cost: Gen. Flagg, Kwinn, Scar-Face, and Dr. Venom are casualties, and Bludd escapes with the Baroness.
