Archivist Maps and Explorer Backpacks in Shadow of the Tomb Raider will reveal all other Collectible Locations on the map! They are very helpful when going for 100% game completion. Then all other collectibles get marked on the map (except Tombs and Challenges). The maps and backpacks themselves don’t count towards 100% completion, they just make your life easier with the actual collectible locations.
- Archivist Map: Reveals all Relics, Murals, Documents Monoliths on the map.
- Explorer Backpack: Reveals all Crypts, Treasure Chests, and Survival Caches on the map.
None of these items nor the collectibles are missable. You can get everything after the story in free-roam. Base Camps for fast travel back to the first map (Cozumel) also unlock after the story.
Below we’ll go through them region by region in chronological order.
Explorer Backpack: At the end of the area, after jumping over the hanging bells, you must shoot a rope arrow to cross over an abyss. Then you can rappel down a ledge and swing onto a platform below. From the distance you can already see a shimmering light because a Survival Cache is also found here.
Archivist Map: It sits in the corridor between the two base camps of this region (where a diving section happened in the story).
Explorer Backpack: In the south-west (bottom left) of Peruvian Jungle. You can only reach this by swimming to it, look for a cave in the water at the foot of the mountain.
Explorer Backpack: Inside the Challenge Tomb.
Archivist Map: Inside a hut on the long path in the north-east of this region.
Archivist Map: Inside the Crypt. This one can be easy to miss. Enter the Crypt and head straight down the long corridor (only one way to go). When the path splits, head right. Then jump over the two traps and up the wall until you reach a lever that opens a gate leading back to the Crypt Entrance. Where the lever is, there’s also a crack in the wall that brings you to a side room with the archivist map. Easy to overlook the crack in the wall, so just remember when you see the lever with the gate look around carefully.
Explorer Backpack: In the south-west corner of the lake at Kuwaq Yaku town, there’s the base camp “Jungle Cliffs”. Next to it sits the Explorer Backpack by a tree.
Archivist Map: In Kuwaq Yaku town, inside a hut on the water, eastern shore.
Archivist Map: Inside the Crypt, after burning down a wooden barricade with fire.

Archivist Map: In the area north-west of Paititi, outside the town. You can enter this section through a muddy path on the west-side of Paititi.
