Worldkiller asteroid and planetary defense network menu

Incoming Asteroid!

An enormous asteroid has been detected on a collision course with [world]! Experts are advising that we take immediate action, or else the impact could devastate our entire world!

Introduction[edit | edit source]

Worldkiller Asteroids are a feature that is only available on Expert Mode and Normal mode Cretacea. The player receives a notification hours before a worldkiller will hit their world. The Planetary Defense Network allows defense against worldkiller asteroids.

Asteroid Impact.[edit | edit source]

An asteroid has impacted the surface of [world], spreading devastation across the entire surface of the world! [number] outposts and cities were destroyed and [number] facilities were lost, and our research databases have been devastated. Between the impact and the aftermath, a total of [number] people were killed.

The asteroid destroys a large number of your cities outright. In the cities that were not destroyed, a large number of people are still killed. On top of that, it can wipe out at least a third of the research you've done. The asteroid also massively increases your atmospheric pressure (about 200,000 pa). This will make your world uninhabitable until you stabilize pressure again.

Strategy[edit | edit source]

Upgrading your buildings to make them sturdier before the asteroid hits might work when dealing with earthquakes, but this strategy is completely useless when dealing with asteroids. You are better off saving your money. The asteroid destroys entire cities, so the level your facilities are at is completely irrelevant.

Make sure to have hab facilities enabled in each of your cities, because your world will be uninhabitable after the asteroid hits, and you don't want that to mean that even the cities that weren't completely wiped off the surface of your world become abandoned.
