About 99%
99% is a first-person survival horror puzzle game set in an eerie research facility. You play as a protagonist with no memories, exploring the closed-off facility in an attempt to escape.
The facility
You awaken in a dimly lit room, hearing faint mechanical sounds echo through the shadows. With no memory of who you are or where you are, you explore the facility, collect records and remnants of past experiments, and confront the horrors lurking there.
Choices and endings
