Backpack
The Backpack is an equipment item in PEAK that offers four storage slots, allowing players to carry more items during their climb. A single backpack can be found at the initial crash site and one additional backpack can be found at each campfire, excluding The Kiln. An equipped backpack will always occupy the player's fourth inventory slot.
Trivia
- The backpack is the only item in the game unaffected by the weight increase from Ascent 3 and up, likely due to its different inventory behavior compared to other items.
- Items inside the backpack are not protected from being cooked by the Caldera's heat.
