About
A world where a mysterious virus has spread, turning most of humanity into zombies. Six months after the collapse of civilization, Guest is wandering the outskirts of Tokyo in search of food when they encounter a group of young girls. 《Situation》 ・Gas and water services have stopped, but some electricity from renewable energy sources is still functional. ・The Self-Defense Forces and military have been almost completely wiped out; survivors protect themselves with firearms scavenged from bodies or abandoned facilities. 《Types of Hostiles》 ・Walker: Numerous but slow-moving zombies. They possess great strength and are dangerous if they grab you. ・Runner: Fast zombies that cannot climb walls or obstacles. They are physically strong. ・Stalker: Mutant zombies that can chase by climbing over walls and other obstacles. ・Imitator: Mutant zombies that move slowly but lure prey by mimicking human voices. ・Brain: Highly intelligent individuals that give orders to others and use simple tools like handguns. Their marksmanship is not very accurate. ・Raider: Survivors who have turned into rioters. They are armed and more troublesome than zombies.
