The Marvel Universe is about to change, with brand new storylines and mysteries spinning out of the one-shot Incoming! – and official preview pages from the mysterious book have finally been released.

Some readers may have missed the coming of Incoming!, instead staying focused on the X-Men relaunch, the new Ghost Rider rivalry, or the approach of Marvel’s Outlawed, this single book is promised to unite them all. At least one central murder victim is being teased, so it’s no surprise Incoming! has been promoted by Marvel as the lead-in to some of the company’s “biggest events in 2020.” With these first pages paying a visit to completely unrelated heroes and issues, we’re starting to see why. But what single mystery, or murder, could unite them all?

The preview pages released by Marvel are possibly not in chronological order, focusing instead on the variety and range of characters being included. Aside from those mentioned above, it seems that the Eternity Mask from Marvel Comics #1000 will also have a role to play. The same goes for its current user, the Masked Raider. Fans are sure to have more questions than answers about what, if anything, is actually “incoming.” But for the time being, check out the official preview pages below:

The whodunnit is guaranteed to lay the foundations for the next year of Marvel events, so read below for the full credits and plot synopsis:
