Marvel's next big event will come in early 2016 with Avengers: Standoff!. Announced at New York Comic Con during the "Marvel: Iron Man & Avengers" panel, this new series kicks off in March with Standoff!: Assault On Pleasant Hill Alpha by Nick Spencer and Jesus Saiz. The story continues on in tie-in issues of Sam Wilson, Captain America; All-New, All-Different Avengers; Uncanny Avengers; New Avengers, Agents of S.H.I.E.L.D; and other titles to be announced.
Here's Marvel's official description:
From the outside it looks like any other remote small town. Only Pleasant Hill is anything but. This gated community holds a dark and sinister secret – one that keeps its residents locked away behind its walls. Now, the time has come for its townsfolk to finally escape. As their revolt begins - why then are the Avengers trying to keep them inside?! And what does it have to do with S.H.I.E.L.D.? Even Earth’s Mightiest Heroes won’t be prepared for the truth behind Pleasant Hill.
According to Spencer, Avengers: Standoff! was originally conceived as a tribute to Captain America's 75th Anniversary in 2016, and the three current and former Caps -- Sam Wilson, Steve Rogers, and Bucky Barnes -- will be the major focus of the book.
