The game, which puts players in control of Captain America, The Hulk, Iron Man, Black Widow and Thor as they play through a new, original story, was previously set for release on PS4, Xbox One, Google Stadia and PC on May 15.
“In order to achieve that goal, we have made the difficult decision to move the release date of Marvel’s Avengers to September 4, 2020.
“When we set out to bring you our vision for Marvel’s Avengers, we committed to delivering an original story-driven campaign, engaging co-op, and compelling content for years to come,” they added.
“To that end, we will spend this additional development time focusing on fine tuning and polishing the game to the high standards our fans expect and deserve.”
“The worldwide teams working on Marvel’s Avengers sincerely appreciate the support you’ve shown us,” Amos and Rosenberg said. “We thrive on your enthusiasm and feedback and we can’t wait to show you more.
“We apologize for the delay. We’re confident it will be worth the wait.”
The publisher released a 19-minute Marvel’s Avengers gameplay video in August 2019.
Square Enix also delayed Final Fantasy VII Remake on Tuesday.
