UPDATE: A former Daybreak employee who wished to remain anonymous had some comments to say about the studio. Apparently the Austin studio was working on an unannounced project. They can't confirm whether this was an MMO or Marvel related, but previously Austin has only worked on MMORPG titles. The project supposedly had to be restarted multiple times and there were layoffs surrounding it. Eventually, senior staff members moved to the new project and there were rumors of it being restarted once again.
According to a post on Reddit several former Daybreak Games employees have confirmed that Daybreak was developing a Marvel MMORPG. According to the post the game was worked on for most of 2018 before it got canceled. This does line up with some layoffs that took place last year.
On the evidence of the MMORPG the Reddit post says this:
“Evidence about the game comes from posts by developers who are working or have worked at Daybreak's Austin studio. There's multiple references on sites like Linkedin to working on a comic book game that's different from DC Universe Online, and one comment even directly references the Infinity Gauntlet. An artist who worked at Daybreak until the layoffs posted art showing off Marvel characters like Red Skull, Iron Man, and Captain America.”
The images in this article are from the supposed artist who was laid off by Daybreak.
Finally, the rumor ends that the game doesn’t seem to still be in development and that one developer wrote the game had top-down issues.
It should also be noted that the Daybreak Austin studio is currently hiring for a new MMO project and the job listings state that they’re working on a world class, iconic IP. But, they don’t mention anything about comic books or anything else that might hint at what they’ve got in the works.
At the moment this is all we have to go on with this rumor. Is it true? We may never know. For now at least we can enjoy some sweet Marvel art.
