Not every game in Sid Meier's Civilization 7 leads to smooth sailing. Countless challenges await, whether it's unruly neighbors that keep denouncing you, natural disasters that damage your buildings, or the fact that you can't find an ideal area with optimal yields. Of course, there are also trials and tribulations brought about by the changing of the times. These are meant to test your mettle as you move from one era to the next. Here's our guide on how to survive Crisis Events in Civilization 7.How to survive Crisis Events in Civilization 7Civilization 7 Crisis Events occur near the end of the Antiquity Age and Exploration Age. What you get at the start of your match tends to be random, but you need to be ready when these occur. There are also policies that you have to consider if you want to mitigate the potential damage, doom, and death that await your empire.There are six kinds of Crisis Events that we've seen so far in our playthroughs, and these are dependent on the current era. The Antiquity Age and Exploration Age have three each; there's no Crisis Event for the Modern Age. Antiquity Age Crisis EventsThese Civilization 7 Crisis Events have a chance of occurring during the Antiquity Age:Revolts - The rising unhappiness of your populace reaches a fever pitch. Soon, your settlements are in open revolt, and everyone wants to oust you.Invasion - This is somewhat akin to the "Raging Barbarian" options in previous games. Basically, countless independent peoples swarm your lands. Even if you've eliminated their last troops, there's a chance that their encampment respawns after a few turns.Plague - The plague during the Antiquity Age is extremely tough to survive as there are few medical breakthroughs at that point in time. Exploration Age Crisis EventsLater during the Exploration Age, you might experience one of these Crisis Events:Wars of Religion - As nations spread their religions far and wide, there will be clashes among disparate groups that believe in their own tenets. It's up to you if you want to show zealotry in your beliefs or if you think it's possible to have tolerance.Revolution - The rise of the bourgeoisie and the middle class comes as a shock to the nobility, who ones held unrivaled power. Now, the people clamor for change and you might even find yourself leading a Revolutionary Government.Plague - While there are more ways to mitigate the plague during the Exploration Age, it's even deadlier and more contagious than before. Expect it to spread rapidly across your empire in just a few short turns. You can learn more about this disaster in our plague survival guide. What are Crisis Policies?Every Crisis Event in Civilization 7 has its own unique set of Crisis Policies. Here's the kicker: A few of these might have a positive effect, but the negative effects are still significantly more pronounced.The reason for this is because Crisis Policies are only meant to stem or mitigate the dangers of the ongoing disaster, not stop them completely. Basically, you have to weigh the pros and cons of each option as you continue to fill the available slots.Here are some examples:Invasion: Tribute - This deducts -10 gold for each city-state that you're a suzerain of. However, assuming most independent peoples are actually hostile and you're not a suzerain, then this won't affect you at all.Revolution: Impoverished Nobility - This adds +1 gold maintenance to all units. But if you're playing a mostly chill and relaxing game with AI neighbors, then you probably don't have a lot of units in your armies.Plague (Exploration): Humoralism - This grants science when Physician units treat the infected in tiles with a Hospital. Now, if you've already built Hospitals in your settlements, then this is a good way to boost your science for a bit. Can you prevent Crisis Events from happening?Crisis Events have a mean-time-to-happen (MTTH). It might take a while until the first incident triggers, but you need to be ready once it occurs. That said, what happens afterward isn't always set in stone. For example:In one of our playthroughs, a Plague Crisis occurred during the Exploration Age. It then spread from a neighbor's capital, and then to two of our nearby cities, all the way to settlements on other continents.When we reloaded our save, the Plague Crisis still happened. However, we had several Physicians ready on standby. We treated the sick in the city that's close to our neighbor's capital. From there, the illness spread to two other settlements, which we also handled. When the Black Death arrived on the other continent, it only affect those that are in one of our settlements. The rest were spared.We should also note that, if you do get the Plague Crises, the best thing to do is to move all your units to (a) unowned tiles outside your empire or (b) water tiles without improvements. That's because the sickness infects urban and rural districts (i.e. anything with an improvement or building). So, if your units are on other tiles, they should be safe for the most part.That does it for our guide on how to survive Crisis Events in Civilization 7.
