Plant vs Undead (PvU) is a blockchain-based free-to-play multiplayer tower defense game that resembles the mechanics of Plants vs Zombies but introduces NFT technology, which many call "NFT for small plants". Another advantage of Plant vs Undead over other blockchain-based games is that there is no investment barrier as it is completely free and unlike other games, there is no payment requirement before players can start playing or have in-game assets that can help them earn rewards from the game.

One of the most important assets the player has in the game is plants. Each plant is unique and can be grown "from seed". Players can also choose to buy or sell their assets on the platform's own marketplace. NFT will provide games with unique features for each player's in-game assets. It also provides owners with real ownership, value, and the opportunity to trade in the NFT market.

The game is a parody of the hugely popular Plants vs. Zombies, which is available on Android and the AppStore and has amassed hundreds of millions of downloads worldwide. In Plant vs Undead, the player must care for plants and protect them from monsters trying to invade the garden. The goal itself is to protect the mother tree, and for that, many plants are required to face monsters that have only one goal: destroy them and reach the mother tree.
