Here, it seems to be being used as a code-name for the treasure/technology/secret/whatever that is about to be found in that Egyptian tomb, which the Egyptians called "Amtoltec." Presumbaly it's the obelisk seen in the first two issues of the story. The double-reference is that "Krieger" is Garrison Krieger, aka General Blitz from the G.I. Joe spin-off "Sgt. Savage," who appeared during the Binaltech storyline.
Bulletman, Predaking, and Hearts of Steel is what has me tied into this series. I'm wondering if Hearts of Steel will tie in to the resurrection of Bumblebee and Shockwave.
I have to admit, it's weird seeing Bulletman. Everytime I see him, I keep asking myself "Why is a DC comics character here?"
Does it still count as a resurrection of they are just being replaced with alternate reality versions? And I know that between Starscream's visions and the theme of this year's annual, a resurrected Bumblebee might happen, but has there been anything hinting towards a resurrection of Shockwave?
Maybe what will happen is that when the Dark Cybertron climax happened, they did not die, but were sent back in time and became the Hearts of Steel versions that the Revolutionaries find.
