Marvel's Spider-Man/Backpacks

Backpacks are collectibles scattered around the city, limited in number and each providing a Backpack Token (which, like other tokens, can be used to craft suits and gadgets). Each Backpack contains an item from Spider-Man's past, allowing you a glimpse of his long career. They can be viewed in the menu, complete with commentary from Spider-Man. Below is a list of Backpacks, the items that they contain, and their locations.

The very first backpack can be found as part of the story mission ../Keeping the Peace/. Using psx: R3 will reveal their locations, represented by a green beam, once you've activated the area's surveillance tower.
