We're very excited to announce that the X4: Foundations "Empire Update" (9.00) has officially launched!

Ship Visual / Modularity Changes Engines and shields are now integrated into S and M ship models. This change improves their appearance and significantly increases the variety of modules they can equip. This change leads to more deliberate, consistent visual identities for ships throughout the gate network. Additionally, S and M ship hardpoint locations have received a facelift, allowing a greater variety in loadout options. For example, Boron and Commonwealth ships can equip each other's modules, and they can now equip smaller weapons and turrets.
