Warning: Spoilers ahead for Marvel’s Spider-Man 2Though many have focused on the big teases from Marvel’s Spider-Man 2’s ending and post-credits scenes, the game sets up two big side villains within its optional content, one of which a fan believes they have spotted within the open-world. Obviously, this is almost guaranteed to be nothing more than a Marvel’s Spider-Man 2 bug, but the interesting footage has still gotten fans talking.
