In March, the core "Avengers" titles will descend on a small, mysterious town called Pleasant Hill in "Avengers: Standoff," where each team discovers a dangerous secret about their allies. Announced this past October at New York Comic Con, the series' details have been kept largely under wraps -- until now. A new set of solicitations and cover images from Marvel.com unveil more plot points and how each title will find itself tied into this Pleasant mystery.

Kicking off with a special "alpha" issue by Nick Spencer and Jesus Saiz, the story is set to celebrate the 75th Anniversary of Captain America as Steve Rogers is assaulted in an idillic town called Pleasant Hill. When the Avengers join the original Cap, the story will thread through several titles including "All-New All-Different Avengers" and "Uncanny Avengers."
