The next expansion of X4: Foundations will be revealed right here on December 20th, 2023, 16:00 CET (3pm GMT / 10am EST / 7am PST).
The most elaborate space sim ever made is getting another expansion/update, most likely early in the new year. Full announcement on Youtube tomorrow Dec 20th at 16:00 CET.
X4 is a great game and definitely underrated imo.
