Set in 2104, it tells of the invasion of Judge Joseph Dredd's city , Mega-City One (MC1) by its Soviet Style counterpart, East Meg One. While the city is still vulnerable, most of the population having been infected by the Block Mania drug , the East Meg forces launch a surprise attack on all fronts, including nuking random sectors of the city. Soviet nuclear weapons are then detonated across Mega-City One's Eastern seaboard, creating a tidal wave that destroys the Atlantic Wall and many sectors.
