ev.io

Ev.io is a free-to-play, web-based shooter that recalls first-person shooter pioneers like Quake and Unreal Tournament—but this one lets users earn cryptocurrency for playing, too. Set in a futuristic world, your character is equipped with a gun of your choice and a melee weapon. You have the option of fighting enemies in a free-for-all deathmatch or battling it out in teams, plus you can dip into a sniper shotgun mode or a survival mode akin to the popular Call of Duty “Zombies” experience. After purchasing an optional Ev.io NFT on Solana and equipping it in-game, you're able to earn an in-game currency called "e.” The amount of e you earn is based on your in-game score, which is primarily based on the number of kills you get. Players can also earn e from events, daily quests, clan wars, and more.
