The Sack Heroes ecosystem will consist of different collections, even though they will be opponents they will only function together. There will be battles between good and evil. These battles will work like a quartet game, where you have to tactically decide before the fight begins which of your heroes or villains you will send into battle. The different traits will have different effects on the opponent and some traits will work better together than other pairings. There will be different battles so that every holder can take part, i.e. 1 NFTvs. 1 NFT, 3 NFT vs. 3 NFT, and 5 NFT vs. 5NFT (NFT`s not Player). Only holders who have not listed for sale a single one of their heroes or villains can take part in these tournaments. Loyalty to the community is paramount here. The expected winnings are graded according to the type of battle, with 5 vs. 5 victories receiving the highest reward level. Rewards will include weapon upgrades for upcoming battles, as well as non-cash prizes such as NFTs, ETH, Sack Heroes promotional items, etc. Sack Town will be a central place where the community meets (chat, marketplace, bulletin board, 3D dressing room) and plays tournaments, and the first Sack Heroes collection minted on April 12th will be the key to Sack Town for each holder. This should serve as a little information in advance, because you can expect a lot more. Be smart, become a hero.
