All Weapon Blueprints’ Locations
To find all 12 weapon blueprints, loot the chests in Vavilov Complex. Players who’ve already exited the complex still have the chance toget the gun plans. But they must investigate random chests in the open world map for that.

The blueprint spawns inAtomic Hearthave a specific order. But their locations are randomized. In other words, players are not guaranteed to find the exact blueprint they’re looking for in these locations. But they will eventually unlock all as a part of the main quest line.
All Modifier Blueprints’ Locations
Modifierblueprints let players upgrade weaponsor craft ammunition. Like weapon blueprints, the only way to acquire them is by looting chests, and there is no guarantee to get a specific one as the rewards are random.

What to Do with Blueprints in Atomic Hearts?
Use the blueprints to craft weapons, ammo, and modifiers (weapon upgrades). For that, visit any NORA vending machines in the safe rooms andopen the crafting menu. But note that each blueprint requires different resources—or ingredients. Players can only build the ones that say “Sufficient Resources.”
