Tower Defense is a popular genre of strategy video games where players must defend their territory from waves of enemies. Players achieve this by strategically placing various types of towers along a predetermined path. Each tower has unique abilities and strengths, allowing players to create effective combinations to stop the advancing foes. As enemies approach, they follow a set route, and players earn resources by defeating them. These resources can be used to build new towers or upgrade existing ones. The goal is to prevent enemies from reaching a designated endpoint, often represented as a base or castle.
