Game Introduction The darkness of the apocalypse shrouds the world, and the ultimate defense battle is already underway! **Zombie Attack: Defense** plunges you into a desperate battlefield swarming with undead hordes with its dynamic 2D art style. There’s no turning back—only a fully upgraded arsenal and the resolve to survive stand between you and annihilation. From rapid-fire rifles to devastating explosive weapons, you will become humanity’s last line of defense. Every wave of attack brings a brand-new challenge: shambling regular zombies, darting speedy raiders, and towering mutant behemoths with unique resistances make up more than 20 enemy types, each deadlier than the last. You’ll need lightning-fast reflexes to land precise headshots, and sharp strategic thinking to turn the tide: lay down barbed wire barriers to slow the onslaught, deploy flamethrower turrets to create walls of fire, or even trigger map-wide oil tanker explosions to turn the environment into your weapon. Difficulty ramps up dynamically as you survive longer. Zombies will unlock fire-resistant and explosion-proof traits, forcing you to constantly upgrade your weapon tech tree and reinforce defensive fortifications if you want to hold your ground against the endless undead tide.

To steadily clear levels, you need to grasp the rhythm of "steady start in the early stage, linked firepower in the mid-term, and adaptation in the late stage". Below are the key survival skills. Early Stage (Waves 1-8): Focus on basic defense and resource accumulation. At the start, prioritize unlocking the rifle and barbed wire. Choose narrow passages or corners that zombies must pass through for defense, and use 1-2 barbed wires to form the first line of obstruction. Use precise rifle shots to eliminate stragglers. Don't over-deploy during wave intervals; reserve resources to upgrade rifle fire rate. Prioritize eliminating regular zombies to avoid being surrounded. The core of this stage is "less is more"—don't blindly pile up defenses, and ensure there are remaining resources to deal with emergencies after each wave. Mid-Term (Waves 9-18): Strengthen firepower linkage and environmental utilization. After unlocking the flamethrower, combine it with barbed wire to form a "slowing + area damage" combo. Deploy the flamethrower behind the barbed wire to maximize the burning range. When encountering speedy zombies, quickly switch to the rifle for precise shooting; when facing a small number of mutants, decisively focus fire with explosive weapons. Remember the location of oil tankers on the map, and trigger area explosions when zombies are dense to clear the field instantly. At the same time, gradually upgrade the durability of defensive structures to avoid core defense lines being breached. Late Stage (After Wave 19): Adapt to dynamic difficulty and resource circulation. After zombies unlock fire-resistant and explosion-proof traits, prioritize upgrading armor-piercing damage in the weapon tech tree, reduce reliance on flamethrowers, and switch to a combo of high-damage rifles + explosive weapons. Utilize light roguelike random buffs, prioritizing gains such as "increased fire rate" and "area damage bonus" to form exclusive combat styles with different weapons. Repair damaged defenses in time during wave intervals; if necessary, "redistribute defenses from low-pressure areas to main routes". General Tips: Always maintain precise headshots to improve horde-clearing efficiency; reasonably allocate aiming and shooting rhythms when using one-handed controls to avoid chaos; reserve 1-2 explosive weapons to deal with sudden boss-level zombies. Follow the cycle logic of "obstruct - output - upgrade", and you can steadily increase your survival time in the endless zombie tide.
