Stellaris

One of three sweaty crises in the game. With random skating rinks, it’s unlikely you’ll ever see one.
To get triggered, you need to fulfill 3 conditions.

1. There should be more than half of the synthetics in the galaxy (the icon of a man with a gear on his chest, that’s them) + 50% to the chance. You can do 25%, but it’s better to strive to make everything synthetic. Why waste time.
2. Be sure not to study the Jump Drive, otherwise there is a chance of triggering another crisis.
3. This item is optional, but it is desirable that there is an extinct machine empire on the map. It gives a chance to trigger.

Keep your fingers crossed and hope the praetors don't come. Since there is still a small chance. But with these conditions it is small.

To try to do everything in one roll, we set up the map like this.

600 systems
3 extinct empires (in case you come across a machine one, I got it. If you don’t come across it, oh well)
1 AI empire. We create them as synthetics on the menu.
0 primitives

We ourselves become materialists and ascend to machines through bonuses for aspiration. We are diligently riveting robots before this.

See the difficulty level for yourself, but if you don’t want to worry too much, set it to cadet. At this difficulty level their max ship stacks are 90k. But also a lot.

It is advisable to prepare 8 fleets of 80-100k each for a crisis. I'll explain why. You make them purely from battleships with disintegrators and arc emitters. At max, install as many shields and storage devices as you like. No armor needed at all.

During a crisis, 4 random points will appear on the map from where these scumbags will emerge. You need to divide the fleets of 200k each and distribute them throughout the galaxy in order to reach the spawn point in time and begin bombarding the planet. There is no need to land on the planet, just bomb for a long time. That's it, easy.

After 4 planets, the 5th one will appear, finish it off and get the trophy.
