Of the 999 Aliens in our collection, there will be 5 special Aliens. These Aliens will be easily distinguishable from the other Aliens, and if you are lucky enough to mint one, you will receive a one-time reward of 5 SOL. Your chances of minting an special Alien are relatively small, but if you are successful, congratulations! Keep in mind that this is a one-time reward, and you will not receive any additional rewards for holding onto the Human NFT.
