In Draw Defence, players fortify their lines by managing resources and constructing towers to slow down advancing hordes of enemies. The goal is to protect one's base from relentless attacks. Players must balance resource management, tower construction, and defences in real-time to prevent enemy intrusion. To succeed, they must make tactical decisions regarding tower placement, resource allocation, and defensive strategies. Draw Defence can be played in a web browser with no need for download or registration, allowing for easy access and seamless gameplay.
