Zenless Zone Zero is Hoyoverse’s new urban RPG that brings a new style of gameplay. Compared to their previous games like Genshin Impact and the Honkai series, Zenless Zone Zero is more casual and is heavily focused on problem-solving. The game is significantly more chilled out and players can take it easy in the land of New Eridu. Players take on the role of a Proxy, a type of service that only certain citizens are privy to when exploring Hollows. With the help of commissions posted on the Inter-Knot, they can traverse Hollows and cities in New Eridu to help people out.
Once players unlock Sixth Street and play through the story, they will eventually come across gold coins. These coins are called HIA Commemorative Coins and can be used to exchange rewards with Sage the Barrel, who is also located in Sixth Street. Sixth Street currently has 18 coins and here’s how to get all of them.
