Lasting 12 issues, it's of note because it's some of the earlier professional work of writer/artist John Byrne's that was published (prior to this, he'd done some Wheelie and the Chopper Bunch issues, of all things, for Charlton)....also, issues #7 through #12 are reprints of issues #1 through #6....
The series takes place in a near future in which a South American despot named Rykos launches his sole two atomic missiles on New York City in the U.S. and Moscow in the U.S.S.R. The two superpowers, each believing the other has launched a first strike, retaliate. By the time American president Cole and a Russian premier with the first name Mikhail have realized their errors, their fully automated nuclear-missile systems can not be countermanded.
Only hours before the apocalypse begins, a Saturn VI rocket launches bearing three astronauts: Captain Boyd Ellis, United States Air Force; his fiancée, Jill Malden; and Japanese physicist Ikei Yashida. Weeks later, after the post-apocalyptic radiation has subsided to safe levels, their space capsule lands upon a melting Greenland ice field, where the three ally themselves with Kuno, a 3rd century Goth revived from his ice-encased suspended animation.
