This guide will show you how to find a Freighter Battle and get a good Freighter in No Man’s Sky.
To start, you have to warp to any random system, and there is a random chance that you will warp into the middle of a freighter battle. It’s better if you warp to wealthy systems as you have a better chance at getting better class/quality freighters.
If it is your first time getting a freighter and you get it from a freighter battle, it will be completely free. It will not be free if you already have a freighter, but the price will be reduced. And if you already have a freighter and the value of your freighter is more than the one you are trying to get, then the trade will also be free.
Once you’ve found a battle, all you need to do is clear all the enemies, and then the freighter’s captain will invite you aboard their ship. You can talk to them to get their freighter if you want one.
Ensure you are trying to warp wealthy systems as they have a better chance of giving you a higher class and better freighters.
Now let’s say that you wanted a sentinel freighter, but the class isn’t what you want it to be; all you need to do is make sure you have a save just before you warp and remember what system you warped to. So you can keep reloading your save and continue warping to the same system repeatedly until you get the freighter you want.
