Hello, this is the developer of The First Foreigner.
The First Foreigner is scheduled to transition to its full paid version alongside a major update on July 10, U.S. time. This corresponds to the morning of July 11 in Korea Standard Time.
This update will also add English language support, so players will be able to play the game in English.
If you have already added the free version to your Steam Library, you will still be able to play the game after the transition. Until the transition takes place, you can still add the game to your Library for free as before.
Thank you sincerely to everyone who has played the game and shown interest in The First Foreigner.
