Tom King has announced that he's nearly finished a new limited series, which, according to him, is one of the most ambitious projects he's ever worked on.

"Working today on the final issue of an insanely ambitious maxi series that hasn’t even been announced yet, which is weird, but everything is weird now," King wrote on Twitter. "Anyway, when we all come back there'll be something hopefully awesome waiting for you all. If I do it right."

King's tweet features a man and woman walking to an elevator, both seemingly heading to a hotel room with a door labeled "15A." The panels featuring the woman are darkly shaded, while the ones with the man are regularly shaded. The artwork is by Jorge Fornés, who illustrated issues of King's Batman run.

King offered no details about the project; it remains to be seen if this is a project with DC Comics or a creator-owned project he is developing. He has, however, teased a Watchmen project multiple times.

King is best known for writing Batman, The Omega Men and Mister Miracle for DC Comics and The Vision for Marvel Comics. He currently writes Strange Adventures, and is working on a Batman/Catwoman limited series.
