Basically a real world MMO zombie survival game that allows you to actually survive. You can bunker down in a presumably safe base of operations. An abandoned house. A movie theater. A mall. A grocery store. You can board the place up. Fortify it to your specifications. Build traps. Scavenge food. Grow food. Accumulate other survivors into your pack. Hell, you can fortify an island. You die? You start with a new character. You can stumble upon your dead character and loot his body, as can others. You can loot other dead bodies. Completely interactive. You have to scavenge and adapt or die.
Sounds good in theory but I'm sure everyone will just start killing each other making it PUBG with zombies. ---
