Nathan Edmondson will write the title alongside artist Matteo Buffagni, reports The Beat.
The writer said that he would be trying to keep the indie flavour that originally characterised the Ultimates line.
An upcoming event called 'Divided We Fall' was also teased at the Ultimate Marvel panel, which will see Captain America go up against the surviving mutant population as he attempts to clean up the country.
It was also revealed that Kitty Pryde would continue to lead that version of the X-Men.
Edmondson is best known for his work on Image Comics' Who Is Jake Ellis? and his run on DC Comics' Grifter following its 2011 relaunch.
Buffagni previously illustrated Marvel's Daken: Dark Wolverine.
