Once Human Top-Up: Crystgin, Battle Pass & Servers

Once Human is a free-to-play open-world survival game where you scavenge a strange, Stardust-warped world, build bases and fight off twisted Deviants. Beyond the survival grind, players spend on cosmetics, passes and shared servers to play with friends. The premium currency, Crystgin, plus Battle Passes and Server Rentals are the most common things to top up, and buying them directly keeps your squad's world running smoothly.
