It lives! You play as Dan Davidson, a high ranking security guard, and is stationed in Sector Omega with a team of 8 guards total. One day you are told by some big shot government man and a a few nervous scientists that Alpha Sector is under code black quarantine. Must be just a chemical spill right? Some following days, in the lower levels of Omega, there is a mass power failure occurs followed by strange alien lifeforms start teleporting in and infesting the base. A few hours of saving lives and taking risks, the military arrives for rescue! Wait...why are they shooting everyone? The non-stop xenian creatures and trigger happy troopers left you and your team no choice but to hide in Alpha Sector where dark and even more unknown dangers await.
There will be a uniform color variation with the zombie cyborg and headcrabbed zombie cyborg. Doctor Death created the zombie cyborgs as a form of guard and programmed others to scavenge and rid of animals, and any resistance against Hell's will.
