This outfit is inspired by the 2017 Secret Empire series, which saw Cap as a sleeper Hydra agent.
Drawing from over 80 years of Marvel history, Marvel's Avengers will include a wide array of iconic outfits, as well as all-new designs. Some outfits can be earned & unlocked in-game, and others will be purchasable. Outfits are purely cosmetic & don't impact gameplay.
Looks really nice, way better than the default look imo.
