Shape Defense is a strategy game where players construct a series of structures to defend against incoming attacks. The objective is to maintain a wall while fending off incoming waves of enemies.
Players create and place shields to block enemy projectiles, managing resources to keep the wall intact. The core mechanic involves timing and positioning the shields to maximize protection and minimize damage. As the game progresses, the intensity and variety of the attacks increase, requiring strategic decisions to keep the structure intact.
