One of the defining features of tower defense games is their emphasis on strategy and planning. The genre is known for its simple yet addictive gameplay, which requires players to think quickly and make decisions on the fly. The goal of the game is to prevent the enemy from reaching the end of the path, which typically results in a loss of health or game over. These structures can range from turrets and traps to barriers and walls. In this type of game, players must defend a specific area from waves of enemies by strategically placing defensive structures along a predetermined path. Tower defense is a popular video game genre that has been around since the early 2000s.
