"Brand new in 2.3 is an official offline mode for PC. If you start the game without a connection, or lose connectivity while playing, you will now be able to continue playing Conan Exiles in single-player.

however, see that the line(s) talking about the necessity of an Internet Connection are produced via some Script Templates. i'm not familiar with your Scripts yet, so i'm not sure of what would be the best way to format updating the Article to reflect this.
with any luck picking to write here is the most appropriate location, as the Forum has more broad sections.
