What does the difficulty levels influence? I'm playing thorugh on normal currently. I found it somewhat difficult in the earlier stages because my soldiers would be out wounded SO long after missions. Now they they are better overall, and have a maxed trained medic, it seems too easy.
I've looked on every tab of every page. Equipment, Dress, etc.. Only the cores show up. No drone weapons or chassis visible. And I've tried using the filter. :/ I am running version 1.2.
