In zombie games you are the only / one OF the only survivors of the apocalypse.

In time your friends will fade. Now with no friends your sanity drains as you go mad. As you grow mad your thinking will be janked so going outside to forage will be a death trap leaving you to die as an indoor shutin as you're forced out of your own mind, as you draw into the inevitable fate of death.
Humanity, its last hope, gone.
And with that, everyone has gone to hell or heaven as we think. was it worth it? GGs
