Gear TD is a strategic tower defense game where players build and upgrade gear-based turrets to defend against waves of enemies. Each turret is represented by a gear with a unique weapon attached, such as guns, rockets, and drills, adding a mechanical twist to traditional tower defense mechanics. To fire their weapons, gears must be connected to triggers, adding an extra layer of strategy to turret placement. Players can also merge gears of the same type to create more powerful versions, improving damage, fire rate, and efficiency. With limited resources, players must carefully decide when to place, upgrade, or merge gears to create the most effective defense. As waves progress, enemies become tougher, requiring tactical decision-making and smart positioning. Can you optimize your gear system, trigger the best defense, and survive all waves?
