Now that you have assembled your first character, you can now begin leveling up the character or their gear by using Juice or Parts. Each new account gets 5 juice for free to start which is enough to level a character to Level 3. To get additional Juice or Parts, go to the dashboard and click on the Buy Juice or Buy Parts button.
From this page, select how much juice/parts you would like to buy, and verify the transaction as long as you have enough neon.
With your new Juice/Parts, you can begin to level your characters and equipment. To level your character, click the level up button on the dashboard for characters.
