- Istanbul & Color Customization - 24 June 2026
New Map: Istanbul, TurkeyAdded Ambarlı, the big container port on Istanbul's Marmara coast. It's a row of long piers running out into the harbor, each one packed with docks.There's plenty of docking space, but the lanes between the piers are narrow, so getting big ships in and out without a jam takes some planning.Color CustomizationContainer colors are now fully customizable in the settings menu.
