Basically, a bunch of spider-men and spider-women (and a spider-pig) come together from different universes and team up to defeat a big bad. The secret wars storyline was a quick 5 issues but I saw more Spider-Verse runs listed in Marvel Unlimited and after looking at them I quickly realized there was a massive storyline from multiple spider-man comic runs that all link up.
I thought I would sample some of the more interesting looking ones but what actually happened is that I read the entire storyline, just a bit out of order. I read all the Spider-Verse storyline issues for:
- Amazing Spider-Man
- Spider-Verse Team Up
- Edge of Spider-Verse
- Scarlet Spiders
- Spider-man 2099
There might have actually been 1 or 2 more series that contributed that I'm forgetting. But all told it was about 30 comic issues over 8-10 different series.
I loved this storyline, especially getting to see so many variations on a theme. Seeing all these different incarnations of Spider-Man was absolutely fascinating.
I highly recommend this storyline if you're interested in Spider-Man.
