Chuck Dixon is killing it -- I counted this guy out in the early 2000s, but here he comes again, doing solid work on G.I. Joe. The MASS Device storyline is proceeding along carefully and suspensefully, as it seems we're finally getting nearer to the reveal of Cobra Commander. A particularly nice sequence Dixon conjured up is where the Baroness herself contracts Cobra assassins to get a killshot on her, a calculated risk that can only be averted by successfully proving the MASS Device's effectiveness. This series is clever, and the visual storytelling by S.L. Gallant is sturdy and workmanlike. This book second in line to Costa-Gage-Fuso's "GI Joe/Cobra" in the IDW "Joe"-verse, but it more than holds its own.
