Strategize, adapt, and survive in the Defence category, a cerebral battleground for tactical minds. Tower defence (TD) reigns supreme here, challenging players to fortify pathways with archer towers, frost mages, and artillery cannons against waves of foes—zombies, aliens, orcs, or even pixelated blobs. Modern twists include hybrid mechanics: merge towers to create overpowered hybrids, deploy hero units with ultimate abilities, or reshape terrain to funnel enemies into kill zones. Beyond TD, real-time strategy (RTS) games task you with building bases, managing resources, and commanding armies to repel invasions. Dynamic weather systems introduce rain-soaked battlefields that slow troops or sandstorms obscuring enemy movements. Endless survival modes escalate difficulty until your last turret falls, while narrative campaigns explore wartime politics and moral choices—sacrifice a village to delay the enemy or risk losing your stronghold? Cooperative multiplayer lets allies specialize roles: one gathers resources, another engineers traps, and a third leads cavalry charges. With mod support for custom maps and units, Defence games are infinite chessboards where every move could mean victory or annihilation.
