Archer & Armstrong Vol. 2: Wrath of the Eternal Warrior

Archer & Armstrong just rides the wave it built up in the first book all the way to the beachhead.  There are little hints here and there that these characters exist in an even larger universe.  But the real surprise for me is that Gilad the Eternal Warrior is Armstrong's younger brother.  I want more of a back story for the Eternal Warrior.  Throughout this whole volume our heroic duo has been on the run from Gilad for accidentally killing the previous Geomancer a Hitler look-a-like.  However by the end of this volume the earth as chosen a new spokesperson in the form of Kay McHenry & the Null have been nullified.
