Snake’s blue period.
Metal Gear Solid V: The Phantom Pain puts us in charge of the Mother Base, where we can develop new technologies and upgrades. In order for a new weapon to be developed, it’ll often require you to have the appropriate materials, manpower, and blueprints. Blueprints can be found all over the world of Metal Gear Solid V: The Phantom Pain and really upgrade your Snake’s arsenal when you manage to collect and develop them.
During Mission 5, when you’re in Wakh Sind Barracks, you can find this blueprint there. Or, after Mission 6, you’ll find it in Yakhoo Oboo Supply Outpost in the west of the map, where there are couches and a table.
During Mission 12, you can find it in Afghanistan Central Base Camp. A bunker in the eastern side of the camp holds the blueprint.
After Mission 6, you can also get it from Aabe Shifap Ruins, East Guard Post, or Smasei Fort. During Mission 7, this blueprint can be found in either Ghwandai Town or Wialo Village.
