MechaChain is a 3D robot combat and space conquest video game called "Mechas". Each Mecha is a collection of NFTs representing robot parts, which can be purchased online using the game's crypto-currency called Mechanium, Ethereum, or by card. Once assembled, these parts give birth to a controllable robot in a PvP combat video game. Players earn Mechanium by winning battles, which can then be used to trade and buy new Mecha parts, allowing them to become the best MechaChain pilot.
