Hi,
I'm on chapter 2. I've upgraded my weapons workbench to level 3 and have built my two preferred weapons to start with, a sniper rifle and the LMG. From what I see, I'd still need to craft one of each type for the last 2 tiers for the perk points, but that would cost a lot of circuit boards, and I don't particularly enjoy expeditions. So I was wondering whether later on enemies would drop T3-T4 weapons for me to loot and use for the achievements, instead of wasting circuit boards? Up to now, the T1-T3 dudes I've been killing were only using T1 weapons.
