What makes it different
Four things about Online: 404 are confirmed by the Steam page and the developers' own announcements. Everything beyond this list is still unannounced.
Phone Crafting System
No recipe book. You search an in-game internet for how-tos — past ads, CAPTCHAs and bad advice.
Open World
The sealed Leminsgale District: a town, forest, lakes and wetlands, roughly 4 km² to scavenge.
Zombies & Base Raids
The locals who stayed behind lost their minds. Fortify your shelter — bolt car doors to wooden walls.
Co-op
Follow the story campaign together or just roam the district with up to three friends.

What the Early Access version includes
According to the developers' Early Access FAQ on Steam, the launch build already contains all core gameplay mechanics shown in the trailer: the first third of the story, co-op, resource gathering, building, crafting, hunting, farming, electricity, vehicle driving, zombies and base raids, and the in-game smartphone with its own internet. You pick one of four characters, each with their own stats and starting gear.
Early Access is planned to last roughly 6–12 months. The full version is set to add new locations, more survival mechanics, more ways to interact with zombies and animals, professional voice acting, and extra phone mini-games. The game is sold at a reduced price during Early Access, with the price reviewed after version 1.0.
