Plant vs Undead (PVU) is a multiplayer tower defense game, where the users' plants are also their real assets. The goal is to combine the Plants vs Zombies with new blockchain technology – NFTs. Each plant is unique. Each plant is equally accessible to everyone through growing Seeds. Each plant can be bought/sell in the marketplace. In the process, the “game” part is the priority. Free-to-play gardeners are able to play and earn real assets. There is no initial investment barrier in PVU.
