SpaceY 2025 is a blockchain-based "play to earn money" AAA tower defense game with NFT. 3D sandbox games provide an open and rich gaming experience, but also provide players with a lot of opportunities to make money while playing. Developed by the Blockfish team, its story is about building and defending a human settlement on Mars. Players can trade NFT-based Martian goods — such as land, buildings, towers, and ores — with other players or sell them to them on the SpaceY 2025 marketplace. As the game progresses, they will not only help humanity become a multi-planetary species, but also aid in space exploration and unravel the mysteries of our universe.
