Here is what's in this save:
Story mode 100% complete(Normal)
All Upgrades purchased
All Costumes ulocked
Game save is 90% complete overall(still have challenges and hidden spiders to complete)
Note: I unlocked Cosmic Spider-man costume with dlc code. If that costume doesn't unlock for you, you'll need to get a silver medal on an unfinished challenge from one of the final three chapters.
