That tease was dropped in a Marvel.com livestream Thursday afternoon as part of the site's "Fantastic Four: World's Greatest Week" event.
It looks like that the official Marvel Games Twitter account is teasing something to do with the Fantastic Four coming to Marvel's Spider-Man on PS4 in some shape or form. Outside of the three paid DLC packs, which each included three new DLC suits, Insomniac also debuted a suit based on Sam Raimi's Spider-Man for free.
"One last piece of very cool news", Penagos said as the Marvel team brought the stream to a close. Extra suits are handily the most common bonus content in Marvel's Spider-Man, and as many fans have pointed out, there are a few strong contenders in the Fantastic Four universe.
"Spider-Man has a long history with the Fantastic Four and even served as a member on more than one occasion". "I can't tell you anything more right now. ut you'll want to keep an eye out for this". Or it could be the costume I'm secretly holding out hope for, which is just Spidey in a Fantastic Four suit with a bag over his head.
What the content might be is anyone's guess, but Marvel's Spider-Man has already laid the groundwork for all sorts of possibilities. It also includes references to these same heroes throughout the game's version of New York City including the Avengers Tower and Doctor Strange's Sanctum Santorum.
The game already includes nearly 40 different suits - 10 of which have some as DLC - so Insomniac definitely has a penchant for adding in as many variations of Spider-Man as it can.
