Ren'Py → Spark(no unzipping) RPG Maker → RPGViewer(unzipping required)

Prepare emulator

Please search for and buy an emulator on Taobao (Ren'Py games use Spark, RPG Maker games use RPGViewer), and ask the seller for install instructions.

Download game files

Download the game's PC package (.7z) from this site.

Import / Extract

First try importing the .7z directly into Spark (no unzipping, lowest effort). If it won't open, extract it with an unzip app and take a look: Has a game folder → still a job for Spark; Has a www folder, or js and data folders → use RPGViewer instead and select the folder containing them.

Run & play

Open the game files with the emulator to start playing. If the archive has a date folder at the top, go one level deeper.

Game synopsis

Try to survive the apocalypse!

World War III was a brutal tragedy—at least for everyone else. But you seem to have been doing quite well during this time, hiding on the upscale rooftop of the Skyhill Hotel... until the biochemical weapon hit, and your good days came to an end.
Now mutants are everywhere, eager to tear you to shreds with their venomous claws. But they can't. Your only problem is: supplies are running out. You have to leave the luxurious rooftop to find food. Crossing the skyscraper is like walking through hell. Danger lurks in every corner, and death follows you like a shadow. But seriously, how should you prepare to face this situation?
It no longer matters. Nothing matters except survival. Time is ticking away.
Open the door.
