Square Enix and Crystal Dynamics plan on releasing Marvel's Avengers next Spring and, in typical Marvel fashion, a multimedia movement is being made out of it. Today, Titan Books revealed to IGN that it is collaborating with Marvel Entertainment, Square Enix, Crystal Dynamics, Eidos Montreal and author Greg Keyes to create tie-in books for Marvel's Avengers. The first of these, Marvel's Avengers: The Extinction Key, is poised to arrive on March 31, 2020, less than two months before the game's launch.

For Marvel's Avengers: The Extinction Key, it seems that author Greg Keyes will be fleshing out the pre-A-Day world. IGN gave a brief summary of the game, revealing that "the novel will follow the Avengers and their allies as they battle an ancient organization called the Zodiac. The Avengers team consisting of Captain America, Iron Man, Thor, Black Widow, and Hulk join forces with other heroes like Doctor Strange, Doctor Voodoo, and SHIELD agents to stop the Zodiac from obtaining a weapon called the Zodiac Key."

What is most interesting about this book is the number of characters it adds to the world of Marvel's Avengers. With the likes of the Zodiac, Doctor Strange and Brother Voodoo slated to appear, the likelihood of them appearing in Crystal Dynamic's game become all the more likely. For now, the only non-core team members we know about are Hank Pym and Ms. Marvel; hopefully, we will be learning about what other heroes or villains will be making an appearance soon.

Tie-in books aren't unfamiliar territory for Marvel as they did something similar close to the release of Marvel's Spider-Man. Square Enix is also starting to dip its toes into book publisher with games like NieR: Automata. The partnership with Titan Books will continue too, as they all plan to release an artbook aptly titled Marvel's Avengers: The Art of the Game on September 1, 2020 with more possibly in the pipeline according to IGN.

Marvel's Avengers will release for Google Stadia, PC, PS4 and Xbox One on May 19, 2020 and can be pre-ordered on Amazon. Meanwhile, Marvel's Avengers: The Extinction Key will hit store shelves on March 31, 2020.
