Heroes TD is a collectible tower defense game where the deck you build determines how far you can go. Collect heroes, build your deck, and use it to win matches. Community play is built in, and the game supports an NFT marketplace where players can create unique digital heroes and trade them with other players. Two tiers of heroes exist: non-NFT heroes are available from the start to provide an accessible entry point, and NFT heroes unlock more advanced capabilities as play progresses.
