Defina Finance is a play-to-earn game on the Binance Smart Chain (BSC) that combines DeFi and NFT elements, allowing players to own and monetize assets they earn playing the Defina game. Defina aims to bring blockchain to millions of players and create a community where users can earn while playing and govern the direction of the Defina game. The gameplay of Defina is set in a future timeline where four rival organizations compete to solve the mysteries of the Vrykos, the game's villain species, which resemble zombies. Players choose their hero from one of the four factions and fight Vrykos in battle. They can engage in different activities like preemptive scouting, scavenging for resources, escorting merchants from one place to another, searching for mysterious relics, and striking the undead's nest. An interesting feature of Defina is that the storyline and background is developed through story writing contests, and is entirely a community effort. The Beta version of the game was released in September 2021 and contains three game modes (Adventure, Arena, Mining). In its roadmap, the team envisions adding different typical play-to-earn games like virtual land sales, a Defina merch store, NFTs, and official Esports tournaments....
