When the air you breathe becomes your biggest fear!
A gas leak has been discovered in a research laboratory in a quarantined area. Inside, scientists are conducting human experiments in order to develop a vaccine that will cure the toxic gas's lethal effect.
After regaining consciousness to the sounds of explosions, you find yourself locked inside, and before you realize who brought you here and what you're doing here, sirens and screams flare up throughout the facility.
You must find your way out of this nightmare and escape from Lab 13 before it's too late, or you will be counting your last breaths!
