VR devices purchased on the official platform can be used to enhance the immersive experience of the game. VR devices can be purchased with $Universe tokens or dollars. ## NFT Characteristics Each card has 4 functions, attack, blood, speed of bullet, and width of bullet, the challenge will fail if the blood is finished. The grades of NFT will affect its strength of function, the higher the level, the stronger the function. ## Token Type **Universe** and **Kepler** ## NFT Mining The staking and mining function of NFT will be opened before Kepler launch, and it will continue after launch.
