You can find Delivery Invoices in the following missions: 3, 4, 5, 6, 7, 8, 10, 12, 13, 14, 15, 16, 18, 20, 21, and 28.
Blueprints are located in these missions: 6, 10, 13, 14, 15, 18, 21, 23, 24, and 28.
When hunting animals, take Quiet with you to increase her friendship level by 2% per deployment. You’ll also need a guide to locate the animals efficiently.
You can bypass the lengthy process of extracting and waiting for resources to convert by building a Forward Operating Base (FOB). Use security challenges on empty FOBs, targeting those with only one platform each. Aim for 60 Support Unit platforms, 60 Combat Unit platforms, and 10 Medical platforms. This setup will provide all the resources needed to construct a fully upgraded Mother Base and a Nuke.
Make sure to complete all resource grinding in one session, as server rollovers at 10 AM Central Time drastically reduce resource gains. If done right you can cut 80 hours of the run.
If a double resource event is active (you’ll see a notification when launching the game), you can cut your runs in half.
Event FOBs are excellent for quickly leveling up your staff, which in turn shortens Key Dispatch Mission times. However, avoid the “Bound Dragons” event, as it requires high-level gear.
The ideal scenario for resource gathering is during a double resource event combined with the Mosquito Event.
