The core gameplay of Castle Overlord revolves around attacking other players in order to gain resources and using these resources to get stronger. By owning troopers, a player can launch an assault against another player and attempt to plunder their wealth. Conversely, the defending player must ward off enemy attack by building castles and towers. Every unit (trooper, castle, or tower) in Castle Overlord is an NFT, and they come in huge variations of visual appearance and battle capabilities. Units may also be upgraded by spending resources. Collect rare NFTs to gain advantage in the battlefield, or simply showcase your unique style!
