Clear a CSAT base and you get with good relations to Syndikat 1k for one anti malaria medi.

Skyward, here's a good way to break the economy of the scenario.
Hoard weapons, at least a full vehicule of them
Bring those weapons to a resistance STASH (not a cache or a shop !)
Transfer the weapons from the vic to the stash via the option when you're inside your vehicule and close enough to the stash. This will get you a lot of resistance relation points
You also need to find howard's research notes (he can be found at the doctor's hidden camp)
when your relations with the rebels are high enough, you can literraly sell and rebuy the notes AT A SHOP for a profit of around 3000$ every time you do it.

I knew about the weapons at the stash (already done that, but lost all my progress while I was doing that :')), but the research notes is a really good tip, thanks :) Is that the first or the second camp after they move with the truck you gave em?
Cheers.

first camp, he'll be sitting next to the hut where the doctor is

Will that not work if they've moved already? Or perhaps the notes will be left behind?

i don't know if the notes spawn anyway, but i'm sure you can find him at the second camp

Much appreciated, I'll give that a try.
