Emit is an ordinary guy, which any of you can be, gets into an abandoned complex. He is awakened by the sound of a ringtone on his phone. The caller appears to be a 911 operator, whom Emit allegedly called the day before. To get out of the complex, Emit will need to get through 10 floors of the bunker - to the generator, and supply electricity to the main exit. Each floor will be a deadly threat. Each of the 10 stages will have its own unique feature, whether it is a special obstacle or an unforeseen circumstance. But for Emit, there will be a limiting factor in the form of time.
