If this thing legit, the Natural Disasters DLC is going to launch on November 29th! The price is pretty much confirmed to be 14.99$. The date was removed from the description.
Natural Disasters will include:
Deep, Impactful Gameplay: Keep your city going through the devastation of several possible doomsday scenarios, from towering infernos to the day the sky exploded
With Great Power Comes Great Response Abilities: Plan for, and respond to, disasters using early warning systems, countermeasures, and new disaster responses such as helicopters and evacuations – finally, a Paradox game where “Comet Sighted” actually means something
Radio Saved the Video Game: Citizens can go Radio Ga-Ga with a new broadcast network, helping to rapidly spread evacuation warnings and emergency alerts – or simply relax to new in-game music stations
An Objectively Good Feature: Scenario Mode allows players to design custom game objectives, including custom starting cities, win conditions, time limits, and more – and share scenarios to Steam Workshop
Chirpocalypse Now: Heck yeah, new hats for Chirper
