Repel waves of undead invaders in Zombie Attack: Defense, a tower defense game set in a ruined suburban neighborhood. Place defensive barricades—barbed-wire fences, spike traps, and electric fences—along winding paths infected zombies will traverse. Each slain zombie drops brain shards, which you use to recruit survivor units—sharpshooters, demolitions experts, and medics—that patrol chokepoints autonomously. Upgrade your defense with heavy turrets—shotgun towers, flamethrowers, and Tesla coils—that you place strategically to eliminate staggering hordes. Later levels introduce massive mutated brutes with acid spit and ground-pound attacks—requiring combined turret barrages and unit support to defeat. Can you hold your ground and preserve your defenses long enough for the dawn?
