As one of Marvel's most popular characters, it's no surprise that there will be several Spider-Man related projects as a part of the upcoming Secret Wars event. And while the Spider significance will extend beyond these stories, the focus here will be on those with the strongest connection to Spider-Man. So something like Civil War, which will probably have Spidey in it, will not be mentioned.
1: Amazing Spider-Man: Renew Your Vows.
2: Spider-Island. With Mayday Parker as a back-up feature. (Counting this as one project because it's being released as one project.)
3: Spider-Verse.
4: Secret Wars 2099. (Might be a bit iffy but it's taking the place of Spider-Man 2099 so I'm counting it.)
