Thanks for the reply. I got close with the shotgun and works as intended. Two more from today:
1. Sniper auto critical on flanked target doesn't seem to be triggering, unless I'm misunderstanding what flanked means. Out of cover = flank?
2. My two highest level characters (6 and 7 I think) have disappeared following completing last mission. Which was ended as normal by all characters entering EVAC square.
Also, when does difficulty ramp up? I've just been running missions in the second zone and with my squad leveled up the basic enemies pose no threat.
