23 MB's a Second - Hard Mode Solo - S Rank
I know this level isn't as difficult as it became for me - but with the current bugs and issues plaguing ready or not's 1.0 cross play release I found it increasingly difficult to actually get this mission done.
The resistance to just about every non-lethal is as brutal as the aggressive hostiles. This update succeeds in giving it a difficulty on par with some of the pain of the scavs from Tarkov - but it needs to rebalance and fix it's non lethal weapons.
The pain of ineffective weapons is outdone only by the absolute slog at the end of a run when you have to bag everything and find the civilians. They didn't come to you in the last version and while they claimed to have fixed it - many npc's continue to hunker down and wait to be found dragging out the most boring chapter of every map (when the bad guys are down).
Ironically I can't count how many times we've just executed a civilian in order to trigger a map end to save ourselves the time and monotony.
