Zombies vs. Sunflowers is a free online tower defense game where you defend your garden against endless waves of shambling zombies by strategically placing combat plants across your lawn. Each plant packs a unique ability, so positioning and upgrade choices matter from the very first wave. Collect sun resources between rounds to expand your plant roster and reinforce weak spots before the next zombie push breaks through.

The game keeps things fresh by throwing different zombie types at you, each with their own health pools and movement speeds. Some tank through your front line while others move fast enough to slip past poorly placed defenses. Upgrading your plants is key – a maxed-out sunflower generates enough resources to fund a full defensive line, while offensive plants deal serious damage when placed in chokepoints. Managing your sun economy while reacting to incoming threats is where the real strategy lives.

Fans of classic plant vs zombie games, casual tower defense games, and hypercasual strategy games will feel right at home here. Whether you're looking for a free zombie defense game to kill time or a plant-based strategy game that actually rewards smart planning, this one delivers. It's also a solid pick for anyone searching for free online apocalypse games, fruit and plant battle games, or no-download tower defense games playable straight in the browser.
