From 1993: Fight! Fight! Fight! MYS-TECH WARS was an ambitious multi-book MARVEL UK crossover (then, as now, all the rage) that, in addition to the core four-issue limited series, also crossed over into a number of other UKverse books.
I always got the impression, possibly entirely misplaced, that the British Bullpen had high hopes that they could bring some of the American books into the fold and make this a truly transatlantic event... but couldn't persuade the US editorial team to play along.
The Genesis books that were official part of the arc were:
MOTORMOUTH AND KILLPOWER Issue 9 (the "it starts here" prelude)
DARK ANGEL Issues 10 and 11
WARHEADS Issue 11
KNIGHTS OF PENDRAGON Issue 12
DEATH'S HEAD II Issue 5
The black and white art in this House Ad was part of the massive, and most impressive, gatefold by Bryan Hitch.
The series wasn't reprinted in OVERKILL, although it was considered for THE EXPLOITS OF SPIDER-MAN. I can't recall whether the crossovers ever appeared either.
