This guide was adapted from a_pharaoh's guide. Thanks!

Note: Before beginning, you need to be aware of two things:

1. First, you will not be getting the full 100% by doing this. It'll give you most, if not all of the win-related achievements, but you'll be left with about 70 achievements you still need to do if you want to go for the full 100%.

2. Secondly, this method does require the Destroyer of Worlds expansion. Make sure you have that before proceeding.

Alright, with that out of the way, onto the guide itself! So, this guide is relatively self-explantory. Basically, we'll be adjusting some settings so that you automatically win once the game starts up.

1. Hit "New Campaign" (of course).

2. There's three areas you should be interested in: the map in the top left, the settings on the bottom left, and the player/enemy settings on the right. So, what you'll want to do is pick the AI you'd like to fight. If you want to knock as many achievements out of the way as possible, pick 4 different opponents you haven't fought yet/don't have the achievements for, and set them to 10 difficulty. Yes, the highest. Don't adjust the % stuff, just leave it at 0%.

3. Now we'll focus on the settings towards the bottom left. First, make sure your number of planets is set to 10. Any map style is fine, I just went with Simple. Also check that your campaign type is Conquest. Next, go to the "Ships" tab, change the part at the top to "Complex", and select everything (I'm not sure if this matters but I did it anyway). The Game Options tab shouldn't matter. However, the AI Options tab is very important!. Here is where you will enable "Nomad Planets", the most important part of this entire guide. Set it to 4/10 and set anything else you'd like to set as well. The other settings shouldn't matter much, but both factions (on the left side of the AI Options tab) and AI Plots are related to achievements so enable those if needed.

4. Believe it or not, you're pretty much done. Before starting though, make sure to click all 10 of the planets so that your team owns them when the game starts! This is important because without Nomad Planets enabled, you wouldn't be able to start the game owning all the planets already. With it enabled though.....well, start the game and see what happens!

5. Repeat as needed for all the different AI types, plots, factions, etc.
