While this isn’t anything DLC related, the team over at Insomniac is still patching the game and adding new suits. This time the suits are references to the Fantastic Four days.
The first suit is a blue Fantastic Four suit with a paper bag over his head. The second is the Future Foundation Suit, that Spider-Man wore when he was briefly with the Fantastic Four. I’m not sure how many people are still actively playing this game (especially since other blockbuster games are right around the corner), but you can check them out today for patch 1.14.
