Millennia Age of Blood

Millennia Age of Blood – Strategy

Let Loose the Dogs of War

This Crisis Age gives you all of the tools you need for a faster Domination Victory if you're already playing a Warfare build like Spartans or Raiders.

Make the most out of the additional improvements that give you Warfare XP. And if you haven't researched Defenses and Discpline on the tech tree, get them immediately. Being able to use “Reinforcements” and “Forced March” is essential for keeping troops alive and active.

Lastly, always make sure to leave armies within the settlements that you take. You can't take over the world if you don't protect your territory.

Planet Crafter Tips and Tricks

The Age of Blood tech tree focuses on maximizing your Warfare XP production through unique improvements and buildings. Winning here is fairly obvious. But if you're not running with a Warfare National Spirit, you'll be playing at a disadvantage. That said, it's not impossible to eke out a win in this Age of Blood.

If you aren't waging war with every other nation, you'll want to focus on ending this Crisis Age as quickly as possible. Luckily, you can accomplish this in two ways.

Let There Be Peace

Knowledge points quickens your Technology Tree's progress, letting you research more in lesser turns. Becoming the leading nation lets you (and the rest of the world) continue into the next Age.

Generally, this is done by fully learning three Technologies. But alternate ages like the “Age of Alchemy” require players to fulfill certain conditions in order to take that route. But if you're behind on war and tech, you're left with one other choice: buying time.

Forge alliances with nearby nations using Envoys and Merchants to gain great benefits. Getting additional Wealth also lets you speed up production if you get the necessary Technologies. At the same time, getting to ask for aid from other nations lets you focus less on Unit production and more on getting as much Democracy XP as possible — and afterwards, progress the Age.

The Age of Blood gives players a taste of how Millennia seeks to elevate the genre. As violent as it is, it's arguably the most straightforward Crisis Ages in the game. There will be more times of crisis down the line, and Millennia Age of Blood is just the beginning
