One day in 20XX, an unidentified virus began to spread, starting in Europe. Those infected by the virus began to attack other humans, driven by extreme aggression and hunger. Within 10 days, all of Europe was paralyzed, and 30 days later, it spread toward Russia and Asia. Now, in 21XX, only a small number of survivors remain. To this day, the virus continues to mutate endlessly, and even more dangerous variants keep appearing. ### Zone Types **Radiation/Toxic Gas Zone** A zone created by the explosion of a nuclear power plant. This area is concentrated with radiation and green toxic gas, containing special zombies; entry is impossible without a gas mask. At the center of this zone lies the nuclear power plant, which contains precious resources such as reactor components and nuclear fuel. However, **something** of boss-level strength resides there. **Ruined City** The most commonly encountered type of zone. **Outlaw Territory** A zone occupied by hostile outlaws. They are mostly found in harbors or abandoned factories. **Outlaw Base** A base where outlaws live. It contains many resources and weapons. **Military Zone** An area that can be entered if you possess a military base keycard. There are many dangerous zombies, but also many valuable resources. A military base sits in the middle of the military zone. While there are many firearms and resources, **something** of boss-level strength resides there. ### Zombie Types More dangerous variants appear in deeper and more threatening zones. **Zombie** A standard zombie. **Crawler** A zombie whose lower body has been severed, forcing it to crawl. Wear lower-body protection. **Bloater** A self-detonating zombie. It is tougher than other zombies but has low attack power. It explodes upon death. Dispose of it from a distance with firearms. **Runner** A fast zombie with flesh and bone slightly exposed. It is physically weaker than a standard zombie. **Spitter** A zombie that spits. Its body is translucent lime green and covered in acid. Its spit is not very fast, making it easy to dodge. It has low-to-medium attack power and inflicts a slow debuff by spitting acidic saliva at the target. **Riot Zombie** An armed zombie that was once a member of a special forces unit. It attacks with a baton of medium attack power. It is quite durable. Break its shield with a powerful melee weapon or kill it with high-powered firearms (Sniper Rifle, Rifle, etc.). **Hazardous Material Zombie** A zombie wearing a radiation suit that has been exposed to radiation. Its appearance is much more severe than other zombies. As you approach, the sound of a Geiger counter rising can be heard. It drops a gas mask upon death. It has medium attack power and is quite durable. **Giant** A zombie whose cells have mutated to an abnormally massive size for some reason. It can destroy buildings and structures. It is extremely durable and inflicts fatal wounds. Dispose of it with air strikes, bombs, or powerful firearms. **Screamer** While not physically the strongest, it overwhelms survivors with sheer impact, screaming and charging rapidly with incredible attack speed. It has high attack power, significant durability, and screams upon discovering a survivor, which alerts other zombies. It has pale skin and sharp, metal-like claws on its hands. **Tanker** A large-statured zombie with an orange hue. It possesses incredible durability and medium-to-high attack power. It is slightly slower than a Runner. Its attack patterns include throwing rocks or tackling to knock targets down. **Fire Zombie** A zombie whose entire body is on fire. It has medium attack power, significant durability, and inflicts a burn debuff upon attacking. **Brute** A more mature version of the Giant. It is smaller than a Giant but larger than a Tanker. It has a massive, green, abnormally muscular physique. It attacks by stomping to cause earthquakes or by throwing other zombies. It is a mid-boss level threat. It has extremely high durability and inflicts fatal damage. Usually, 2 to 4 Tankers are found wherever a Brute is present. ### Outlaw Types Hostile factions. They are hostile to both zombies and survivors. **Melee Weapons** *Crowbar / Dagger / Baseball Bat* Outlaws armed with melee weapons. They are not particularly durable. *Chainsaw* They chase you down terrifyingly and frantically with a chainsaw. Because of the chainsaw, their attack power is significant, and they are fast enough to dodge bullets. *Juggernaut* An outlaw armed with a sledgehammer or a fire axe. They have significant durability and attack power that causes serious injury. **Firearms** *Revolver / Shotgun / AK-47 / Uzi* Outlaws possessing firearms. Their durability is low, but their attack power is high because they use guns. *Juggernaut (Minigun)* A Juggernaut equipped with a minigun. It has significant durability and attack power that deals fatal damage.
