The Demo Is Temporarily Unavailable

Some players have recently encountered a compatibility issue that can prevent certain vehicle parts from being installed, blocking progress in the demo.

The issue appeared after the vehicle parts were migrated to the new database system. Since it does not affect every player, I need to review the system carefully to identify and fix the exact cause.

To prevent more players from encountering this problem, I have temporarily disabled the demo while I complete this review and continue working on the next major update, including the new mission system and story mode.

The demo will return once it has been fully tested and properly represents the current state of the game.

Thank you for your patience, for playing, and for reporting the issues you encounter.
