These upgrade points can be used to apply a number of upgrades (over 20 different ones) to the backpack to improve its functionality. This mod provides Minecraft players with tiered backpacks (Basic, Iron, Gold, and Diamond), each of which can be upgraded from the previous tier to give more storage room and more upgrade points. Iron Backpacks Mod 1.12.2/1.10.2 attempts to address the issue of portable storage in a balanced, fun, and aesthetically-pleasing manner.
