Epsilon

Epsilon Labs have been experimenting on subjects for many years. Their latest experiment was both a success and a failure. You, Patient Psi, were successful. Your survival is determined by the well-being of the neonate attached to you. If it becomes distressed, you will slowly succumb to the darkness, taking the neonate with you. You rely on each other for survival.
Not all is bright and cheery in Epsilon Labs. The 'failed experiments' lurk the ghostly corridors in the absence of light, stalking their prey. It will instantly hunt down anything that makes the slightest of sounds, and eliminate it from existence. You must escape.
