In this scan, the order of the pages has been changed
for the benefit of story continuity.

In the original book the Night Zero story (2000AD#0615-20
to 2000AD#0615-24) is placed between 2000AD#0615-14-15
and 2000AD#0615-16.

So the Night Zero story is placed directly after the page
join, and the Dredd story continues after the end of the Night Zero story.
