EDIT @ 10:00 AM PT: An earlier version of this story referred to "Last Days" as a miniseries rather than a branding several other series will run under.

Following yesterday's "Secret Wars" revelations, Marvel has released a teaser hinting at what readers -- and the heroes and villains of the Marvel Universe -- can look forward to as the publisher braces for the coming mega-event.

According to the teaser's accompanying press release, "Last Days" is one of three branded groups of series that will run alongside the main "Secret Wars" title. "Last Days" will focus on the question of what you would do if it was your last day on Earth -- and you knew it.

"Before a new chapter can begin, this one must end," states the text-based teaser, referring to the coming Incursion which will find a number of Marvel's realities co-existing on the soon-to-be-formed Battleworld, with the 616 and Ultimate universe being the ones most discussed during yesterday's press event. But does the use of the word 'end' mean the entire Marvel Universe is coming to a close only to be restarted?

"Read and find out," Marvel's Editor-in-Chief Axel Alonso said of the possibility of a reboot. "Like I said, we are taking some chances here, but I will stand by -- I think Tom [Brevoort] will back me -- our history's not broken... If anything we think we are building upon that history and we are taking the best and biggest pieces of it and seeing how easily they coexist with one another. We don't expect all our moves to make everyone happy, but we think it will make for a really fascinating read."

Official Press Release

The skies go dark and the world begins to fracture. Secret Wars is coming, and with it the destruction of the Marvel Universe as we know it. Today, Marvel is proud to announce LAST DAYS, the first of three different types of series taking place during the upcoming, highly anticipated Secret Wars!

"What would you do if you learned today was your last day on Earth?" says Marvel Editor-in-Chief Axel Alonso. "That's the question your favorite Marvel heroes are going to ask themselves in their LAST DAYS story lines as they brace for Secret Wars and the end of the Marvel Universe."

Battleworld is set to transform the Marvel Universe as you know it. But before Secret Wars can begin, this chapter must come to a close. What will our heroes do with their final hours? What secrets will be unearthed? Who will they want to spend their LAST DAYS with?

"LAST DAYS is the first of three new brandings for series unique to Secret Wars," says Marvel SVP Sales & Marketing David Gabriel. "Each branding will bear its own unique trade dress and logo treatment, clearly defining its relationship to the main Secret Wars story. This will make it easier for fans to experience the full scope of Secret Wars. Don't dare miss these epic tales as our heroes face their impending obliteration!"

Before Secret Wars can begin, the Marvel Universe must end. And it all starts this May as the entire planet faces their LAST DAYS!
