"Give me weapon plans and I can build any weapon known to man. And then some more." - Wolfpack's gunsmith
Blueprints are rare items with randomized drop chance. You have to collect all the blueprints of a certain weapon to unlock it. It is worth it, trust us.
“DNA Parts” are a special kind of blueprints. They are used in creation of new powerful zombies in Bestiary in Skirmish Ops.
- Blueprints were added in 0.4.0 update.
- The whole weapon system was changed in 0.5.0 update. Every weapon can be completed by blueprints.
