GRID DEFENSE is a fast, hand-tuned tower defense game about one simple job: hold the line. Six towers. Seven breeds of creep. One winding path. Place your defenses, upgrade under pressure, and stop everything the grid throws at you across 25 escalating waves — then push into endless mode. FREE TO START Download and play the first 10 waves free. Clear wave 10 to unlock the complete game with a single one-time purchase. No ads. No timers. No subscriptions. THE FULL GAME UNLOCKS • All 25 waves + endless mode • A second battlefield — The Quarry, where terrain fights back. Golems terraform the ground as they march, ore pockets pay out gold when cracked, and a keystone wall splits the map — hold it or watch the shortcut open • Tower-smashing GOLEMS — armored bruisers that stop to wreck your towers • WARDENS that raise energy shields — burst them before they recharge • A deployable DWARF hero — a roaming gunner only the wasps can touch, who levels up to repair wrecked towers and mine ore for gold • Bosses and the final victory stand • The global online leaderboard — submit your score and claim your rank SIX TOWERS, EVERY ONE USEFUL Gunner, Cannon, Frost, Venom, Tesla, Sniper — each with upgrades and a role. Freeze a swarm, chain-zap a cluster, poison the tanks, or snipe through armor. There's no single right build. AN ORIGINAL SCORE A title theme by IVEM BEATS plays you in, and every tower fires its own sound — know what's shooting without looking. BUILT FOR TOUCH Designed for the phone from the ground up — tap to build, tap to upgrade, pinch and pan the battlefield. The board fills your screen edge to edge. Landscape, smooth, and playable offline. No ads. No subscriptions. No login. Just you, the grid, and the line you have to hold.
