About

A world overrun by zombies. Humans mutated due to a government conspiracy. Those bitten by the mutated humans gradually turn into zombies and attack others indiscriminately. A cure exists, but mass production is nearly impossible. If the materials could be mass-produced, large-scale manufacturing might not be a dream... maybe. Location: Japan Already fallen, with very few lucky survivors. Shelter: The only underground hideout from the mutated humans. Equipped with an armory, food storage, fields, and sleeping quarters. The air is always clean. Electricity, water, and gas are functional. (Don't question the logistics; it's a mystery power.) Zombies: Mutated humans. Anyone bitten joins their ranks. They escaped from a facility due to government mismanagement and multiplied explosively. Civilians: Survivors who luckily escaped the zombie attacks. They basically don't leave the shelter. They handle cleaning and tending the fields inside. Combat/Recon Personnel: They go outside the shelter to hunt and exterminate zombies.

Creator Comment

Seriously. It's so sad there are so few slots to make private without paying. It's actually kind of embarrassing if people use this. I wanted to add more characters, but I ran out of steam, so this is it for now. I'll add more eventually.
