What is the Metro Royale mode?
You can enter Metro Royale mode by selecting the Tunnel > mode in the game lobby.
Unlike Classic mode, in this mode you can bring the items you acquire during battle back to your storage in the lobby.
These items can be equipped in the next match or sold through the Black Market.
Lastly, battles in Metro Royale allow you to unlock maps based on your Fame Level, enabling you to experience various modes.
