This guide will let you know how to get a Free Freighter in No Man’s Sky.
The only thing you’ll need for this is a ship with a hyperdrive; it is also recommended to have an economy scanner and a conflict scanner so you can warp to wealthy and high conflict systems. So not only do you have at getting a better fee fighter, but you also have a higher chance of a freighter/capital ship battle appearing in the system you warp to.
All you have to do is warp around to different systems on your star chart until a freighter battle spawns. You have to help the freighter by killing the attacking enemies, then you’ll go onto the ship, speak to the captain, and he will give you the freighter.
However, it has to be your first time getting a freighter to claim it for free, so if it isn’t your first freighter, then it won’t work.
The freighter spawns can be a bit ridiculous at times, so it’s probably going to take you some time before a freighter spawns in.
