Advanced Nukes:
The base damage reduction is:
- 20% for city, forest and jungle
- 40% for hills
- 100% for peaks
But the system is very complex. Lets have a look at an example. We will nuke the plot in the middle with a H-bomb (Nuke Radius 2; not part of CCV at the moment).
And that is the result.
As you can see the nuke explosion looses power from inside to outside. The minimum damage is 10%. The intervall over the whole explosion area is 35% - 135% damage. But the terrain may reduce the semi random part of 25% - 125%.
The plot in the middle is flat land. So there is no reduction from this plot so it suffers from 10% + 25% + 2*33% + rand(0%-34%) damage.
The plot in the south has also no terrain protection because the center plot is flat land and the plot itself is flat, too. So it suffers from 10% + 25% + 1*33% + rand(0%-34%) damage.
The plot in the north of the center has a forest and so the damage is 10% + (25% + 1*33% + rand(0%-34%)) * (100 - 20) / 100
The plot in the northeast of the center has a forest and hills; so the damage is 10% + (25% + 1*33% + rand(0%-34%)) * (100 - (20 + 40)) / 100
So it should be more clear for plots near the center.
Now lets have a look at two plots in a distance of two! The plots in the west and east are easy to explain.
West:
The explosion comes to this plot over the center plot, the three peaks and the plot itself. Three reduction lines! So the first reduction comes from the center plot. But here 0%. The second reduction comes from the line of the three peaks. The reduction is (3*100%)/3 plots = 100%. So the plot behind this wall will only suffer under the base damage of 10%! It doesn't matter in this case what the terrain of the plot itself is.
East:
The explosion comes over the center plot, the three hills (one with forest) and the plot itself. So the reduction of the hills line is (60% + 40% + 40%)/3 plots = 46%. This what the explosion will loose in this line. But because the target plot itself is flat there will we no reduction of the left over explosive power. If it had been a hills plot the explosion would have lost again 40% of its current strength here.
So this system is very intuitive. And as you can see the results are fantastic. This is what you should expect. And it is even better for the AI because human sometimes attack the plot next to a city for maximum damage while the AI always attacks the city. With the effect of loosing power by distance and terrain the AI behaviour makes more sense. And it allows to simulate different kinds of nukes in a perfect way.
By the way the destructive power against buildings and improvements as well as the damage to population also depends now on the distance to the explosion!
New features always trump old saves (at least in my case). 
) I will start a new game and see whether I will see it there (before researching it).
What's going on here? You really haven't got the buttons. They should be there and they also should not disappear. I don't get it. 
! Will you include it in your next patch?
