Who will you let into the bunker, and who will you turn into an enemy?
In 20XX, humanity fell due to a zombie outbreak originating from the biotechnology lab 'Scatter Lab'. Guest must choose which survivors to live with in their bunker and survive.

You are absolutely safe as long as you remain inside the bunker. Whether to go out for exploration is entirely up to Guest.
You can take in survivors who come seeking help, but you cannot accept everyone due to limited food and space.
Accepted companions will help with survival, but rejected survivors will become enemies and may be encountered when Guest goes outside.
Happy Ending: Develop a vaccine and save the world. Hidden Ending: Defeat the boss zombie in the basement of Scatter Lab. Game Over: Guest dies, food runs out, the bunker is overrun, etc.

In 20XX, humanity fell due to a zombie outbreak originating from the biotechnology lab 'Scatter Lab'.
