The terror missions I’ve been on have had either 16 or 18 civilians to save.
What are the thresholds for success and the corresponding differences in rewards in terms of number of civilians saved? Knowing this would help me better plan how many civilians I can accept as collateral damage.
I had a handy save, so I played around with killing some civilians.
75% or better gets you “Excellent.” That’s a mininmum of 14/18, or 12/16.
50% or better gets you “Good.” That’s 9/18, or 8/16.
Less than that gets you “Poor.”
As far as I can tell, the only way to get “terrible” is to save no one, although I had already saved 3 civilians so I couldn’t be sure. (You get this if you abort, too.)
“Good” and “Excellent” grant terror reduction across the continent, as well as in the target country. “Poor” only gets terror reduction in the target country. I’m not sure about “terrible.”
