I’ve been trying to get past these two for a while now, every time I fail.
I can defeat them with ease, but they revive to fight on.
Sally is particularly hard to defeat, her poison cloud ends the fight before it really starts.
I’m actually at the point where I wish I could avoid shooting her so the poison cloud doesn’t appear, but it doesn’t work like that, unfortunately.
So I am recommending/requesting these enemies be removed from the first five battles in the first Wave, to stop making them impossible to get past.
