I had no trouble buying a full set of level 1 and 2 upgrades for my mother base. However, the cost of upgrades balloons by level 3 - it takes 16k in two resources. I've filled my base development unit with highly rated soldiers, but that doesn't seem to increase my material acquisition enough to afford the upgrades. I can:
- gather processed resources in the field, but at 50 to 100 a pop... that's not particularly efficient.
- fulton the shipping containers for 750-7500 unprocessed resources, but these seem to not be so useful as my mother base currently processes resources at roughly the same speed as it generates its own.
What can I do to generate resources efficiently? If I can barely afford level 3 upgrades, I shudder at the thought of level 4 prices...
