As previously announced, Marvel Ultimate Alliance 3 will be getting free costumes for Captain Marvel, Hulk and Spider-Man on Aug. 30th, 2019. We also know that some paid DLC is coming on Sept. 30th, 2019, but it seems we might expect some more free costumes around then as well. Some wording on the official Japanese hub page for Marvel Ultimate Alliance 3 points to free content coming out prior to 2020, but we don't know who will be getting costumes. We'll just have to hang in there for more details moving forward.
More free content coming?
