About 18th Floor
18th Floor is a horror game set in an unfinished building shaped by the hacker known as the ghost. You search its rooms for abnormalities, passcodes and a way out while trying to escape the world the ghost created.
Observe the building
The 20th and 19th floors are model rooms. Watch the environment carefully: signs such as a sudden chill, an ominous echo or blood seeping from a wall may signal danger. If you find an abnormality, turn around and leave immediately. If you find none, do not return.
Find a way out
Search for a passcode that can unlock freedom. When you find a computer, enter the password to try to break the ghost's curse. The door to Room 0 is locked, and finding a way to open it is your only route to escape.
The ghost's story
The ghost used her code to create a lonely, frightening world in the unfinished building. She turned herself into code and remains imprisoned there. Her loneliness spreads like a virus to everyone who enters the 18th floor; escaping is the way to understand her pain.
