Unlike most RPG games, Atomic Heart takes a different approach towards weapons and other items. You cannot simply walk up to a weapon, pick it up, and start using it. You’ll have to unlock weapons via blueprints, and the same applies for weapon upgrades. You’ll have to find the blueprints first, unlock the item/upgrade and only then can you add it to your weapon. Weapon blueprints can be found in chests, and this guide contains the locations of every blueprint in the game. Let’s begin!
