IDW's Infestation event continues here in this two-part G.I. Joe tale! A robotic arm of unknown origin has been discovered and both the JOEs and COBRA race to discover its secrets. Little do the two sides know that the arm has its own agenda- assimilating the world's military technology into the Infestation fold! A secret underwater COBRA base full of B.A.T.S. sounds like the perfect place to start!
