After Tomorrow is set in the future. At that time, science and technology were developed and transportation was very convenient, but it also gave destructive viruses an opportunity-viruses ravaged all countries and human civilization was almost destroyed. In order to "survive" in the last days, like-minded partners gather together to survive in a world where viruses are spreading, infected people are everywhere, resources are limited and the weather is bad.

"After Tomorrow" (code name: survive) is a multiplayer mobile game independently developed by Netease. In the game, players will be placed in the wasteland world after being attacked by the virus. In the face of infected people transformed by the virus and the harsh living environment, all players will compete for limited resources together.
