ShootGun is the world's first Free-to-Play NFT multiplayer mobile shooter game that anyone can start playing without having to pay. ShootGun also uses the Play-to-Earn model to reward players with tokens and equipment through dynamic gameplay and PvP tournaments. With this simple combination of F2P and P2E models, we give players the ability to play and receive rewards at the same time. To create a friendly environment for F2P players who are unfamiliar with the cryptocurrency and NFT market, a mechanism will be incorporated into the gameplay to encourage such players to do their own research and start learning about the crypto market. In ShootGun gamers can play for free and earn metaverse tokens with the help of their gaming skill and participation in the ecosystem of all iDos Games projects. In ShootGun players fight in arenas in various modes. For that players receive daily rewards in tournaments, battles with a bet, NFT tokens, and their sales on the in-game marketplace.
