Online: 404: What You Need to Know Before Playing 

Survival games tend to ask players to gather resources, craft items, construct a shelter and fight off threatening enemies. Online: 404 is built on that same premise, but adds an element of novelty: the most vital tool for survival is your character's smartphone.

Online: 404 is an open-world survival game developed and published by Cornfield Games set in the abandoned  Leminsgale District. Rather than relying solely on traditional crafting menus or a basic survival manual, players use an in-game internet service to search for information, find crafting recipes and learn how to approach unfamiliar situations. The phone is also a functional tool, featuring a map, flashlight and weather forecast.
