Marvel is adding a ninth issue to its core Secret Wars miniseries, the company announced today.  The final issue, by the same creative team of Jonathan Hickman with art by Esad Ribic, will ship with an Alex Ross cover in December.

Delays on the series early this summer had a ripple effect, delaying 53 issues in the gigantic crossover event (see “Marvel Delays Hit Collections, ‘Secret Wars’”).  The extension of Secret Wars by another issue will not have a similar effect, according to Marvel SVP Sales & Marketing David Gabriel.  “This extra issue will not affect any of the new launches as part of All-New, All-Different Marvel,“ he said. “But there might be a surprise or two left over from Battleworld you weren’t expecting. In fact, like the original Marvel Super Heroes Secret Wars, some of those puzzle pieces will hit the Marvel Universe before the event concludes. But if you want to see how they all fit together, you don’t want to miss these last few issues.”

Marvel has been dominating the sales charts this summer, with its Secret Wars titles (and Star Wars) leading the way (see, for example, “‘Secret Wars’ Helps Marvel Dominate Again in June”).
