EGGRYPTO X: Treasure Island Adventure has opened pre-registration on Android and iOS. The new GameWith NFT RPG combines monster breeding, idle progression, equipment hunting and massive cooperative battles.
The game is scheduled for fall 2026 in Japan. The App Store currently lists November 30 as an estimated release date, although the developer still gives only a “2026” release window.
Monsters keep evolving when the app is closed
In EGGRYPTO X, players visit an island guarded by enormous creatures called Giant Gods.
Monsters hatch from eggs and can be sent on adventures that continue progressing even when the app is closed.
When players are online, they can also participate directly in attacks to speed up monster evolution.
Inheritance system changes monster abilities
A major gameplay system allows monsters to receive inherited abilities from other companions used on adventures.
Different combinations can unlock new abilities and even awaken ancient creatures.
This means two monsters of the same species could end up with very different builds.
Trailer:
Cooperative raids for up to 20 players
Players can assemble a team of five monsters and take on the Giant Gods in cooperative raids with up to 20 participants.
These battles reward treasure that serves as equipment and changes a team’s performance. Some rare items also use NFT technology.
EGGRYPTO X will be free-to-play, with purchases available in the app and through the official store.
Pre-registration is already open on Google Play and the App Store. Registered players will receive a ticket for a 10-pull summon when the game launches.
