Volume II begins with a synopsis of Volume I.
The key points:
1) Jason Crater leads a force of musically gifted anti-alien commandos called XT Forces (those aboard the Argo are Argonauts).
2) The Argonauts have been ordered by the dastardly Defense Secretary P. Elias Delmar to capture the Golden F.L.E.E.C.E. from the far side of the moon.
3) Despite all signs of divine approval and getting some love in the process, Jason and the Argonauts have had a rough go so far, and a pair of killer asteroids is threatening all life on planet Earth.
4) Jason struggles to maintain unit morale as they continue on the adventure having just lost three key crewmates, one of them abducted by the alien foe.
