Invincible Iron Man, Vol. 1 #18

Tony Stark has fled to Afghanistan, the birthplace of Iron Man. He's converted the cave in which he created the first Iron Man suit into a lab, and now that first suit is the only one simple enough for him to operate. But it was far from his most sophisticated design. A H.A.M.M.E.R. computer-jockey has picked up his repulsor signature, and Norman Osborn is on his way for a confrontation.

But back at Avengers Tower, someone close to Tony has infiltrated Osborn's lair and is preparing to break out both Maria Hill and Black Widow.
