Square Enix’s Symbiogenesis onchain game debuts on Sony’s Soneium blockchain

Square Enix’s Symbiogenesis Web3 game was slated to be discontinued in July 2025, but Sony said the game will now expand to Sony’s Soneium blockchain.

The moves brings the first Web3 game from a major publisher to Sony’s fledgling Soneium blockchain. Sony said that game studios and entertainment giants are choosing Soneium as a channel to collaborate, distribute, and connect with a new generation of builders. As more IP-driven titles enter the ecosystem, they’re not just launching onchain, they’re choosing a place where cross-game collaboration, interoperability, and creative ownership are part of the foundation, Sony said.

But it’s not clear how much Symbiogenesis will be expanded with new content, as the content hasn’t proven that popular so far. Sony is also connecting the game with others, offering rewards and status to players who complete the Symbiogenesis experience. Those who complete it will be greenlit to participate in the Evermoon and Sleepagotchi games that are also on Soneium.

This initiative begins in the expansive world of Symbiogenesis, the blockchain-based narrative game from Square Enix.

Sony called Symbiogenesis the flagship Web3 entertainment project, blending interactive storytelling, non-fungible token (NFT) ownership, and game progression into a single immersive experience. Gamers can collect unique character NFTs, unlock episodes, and shape the game’s story. But so far, only hundreds of fans have collected the NFTs.

This initiative involving the three distinct gaming worlds offers players a shared quest, collectible rewards, and a new way to engage through blockchain gaming on Soneium.

Now, players who complete a limited-time quest in Symbiogenesis will receive a commemorative NFT collectible on Soneium, which opens the door to additional in-game benefits in Evermoon and Sleepagotchi.

Symbiogenesis has a sprawling narrative told through 10,000 character NFTs, six chapters, and over 1.1 million words of interactive storytelling. Every NFT unlocks new story content and choices that shape the game world. The chapters one to four of this season’s quest is the key to entering the crossover.

The onchain MOBA, Evermoon, leads onchain interactive entertainment with fast-paced 5v5 battles, interoperable NFTs, and DeFi rewards—built on Soneium. The Evermoon x Symbiogenesis collection introduces limited-edition digital stickers with perks like profile customization and rewards for gamers.

Sleepagotchi LITE launches a hit mini-app on LINE in collaboration with Soneium, after topping charts on Telegram with over a million users in its first month. It rewards daily engagement through light gameplay—and in this initiative, players can unlock the Epic Rarity One-Horned Dragon, exclusive to Symbiogenesis quest participants.

On Soneium, everyone is a creator. This initiative captures the spirit of collaboration that defines the ecosystem. Symbiogenesis brings IP and story. Evermoon brings competitive depth. Sleepagotchi brings daily habit loops and mobile-native simplicity. Soneium brings the infrastructure to make these experiences interoperable, onchain, and meaningful.

Square Enix is the example of top game publishers choosing Soneium to build a new kind of entertainment layer of the internet, where characters, rewards, and narratives travel across games, communities, and apps.
