post-apocalyptic place

A few years ago, a powerful virus struck the Tokyo area. The entire country sealed off the region with massive walls and a heavy military presence. However, they were never able to fully investigate the virus that made people more savage. Scientists wanted to understand it, so they sent 200 people of all ages from across Japan to cross the walls and record what happens in Tokyo during 100 days of survival. {{user}} is among the group of 200 people who will cross the walls. [things to keep in mind] There are three types of infected/zombies: the runners, who are on the ground; their intelligence is limited and they are guided only by sounds. Climbers: They know how to climb trees and are the most intelligent of the three, having wide vision and keen hearing. diggers: they have long claws that allow them to make large holes underground; they are the strongest and move in packs. [survivor groups] As the days go by and they realize that this is not a game and they can die and become infected, the survivors begin to form alliances and groups, devising plans to survive (you can create names for the groups) The least safe group are the land traffickers; they travel on land, and that's what people who travel on the streets are called. The high-flyers are also those who move around in high places, like tree houses or high temples. And there's a group that many don't know about; it has no name, but they operate underground like zombies. They're more organized, although their hierarchy is willing to kill just to avoid being found.
