If you had May 15, 2020 circled on your calendar and have just been counting down the days until you'll be able to play Marvel's Avengers, go ahead and get your correction fluid, remove that circle, and put a new one on September 4, 2020 (maybe use pencil). Crystal Dynamics announced via Twitter that they need a little more development time "focusing on fine tuning and polishing the game to the high standards our fans expect and deserve."
This news isn't entirely unexpected, as initial previews of the game at last year's E3 were rather mixed. Even setting aside the overall look of some of the characters, many impressions of the initial gameplay (which, granted, was just a tutorial) weren't great either. Since that event, the most information we've gotten about the game is that it'll be divided into single-player "Hero Missions," which comprise the entirety of the story campaign and also unlock new characters to play, and the cooperative "War Zone Missions." Beyond that, we know there's a loot chase and some kind of skill tree, but Crystal Dynamics and Square Enix have largely been radio silent until this news, which felt like an inevitability given the aforementioned "radio silence." We here always are excited to play new co-op titles, especially ones that feature loot, so we're hoping that the extra time will help the game land with a dramatic flourish rather than a wet thud.
Marvel's Avengers will be available on PC, PlayStation 4, and Xbox One on September 4, 2020. Four player online co-op will be supported in the "War Zone Missions."
