Hey guy, I like do know what in your opinion, a post heavy nuclear blasts earth would look like?

I mean, the geography would change? maybe tectonic anomalies generating raging giant vulcanoes?

How much time the planet would take to "stabilize" and start do generate life "if it would be possible" again.

I'm planning to design a map with theses charcteristiscs, and populate it with Demons, Vampires e Suvivor Humans as well. With low technologic level.

Thank you!
