The current state of MetaShooter can be described as "pre-beta." The process of development is still ongoing. You are not required to have NFTs in order to play the game while it is in the alpha stage. However, having NFTs enables you to hunt more efficiently and earn better rewards.
Because NFTs are integral to the gameplay of MetaShooter, you won't be able to hunt in the game after the full version has been released unless you have them.
