Egosoft released X4 on 30 November 2018 as the first X game where you can fly every ship, walk around stations and build stations of your own module by module. Ships come in four sizes, with S and M built and sold at Wharves while L and XL come from Shipyards, which decides where a damaged fleet can actually be repaired. Expansions have widened the map considerably since launch, adding the Split, the Terrans, the pirate space around Avarice and the Boron kingdom.
Choosing the right build shapes your entire experience. This guide breaks down every option: what they're good at, what they struggle with, and which one matches your playstyle. For optimized builds with full gear sets, see our builds guide.
