The Horizon scientific research center is a deceptively quiet place. When you came round, there were hundreds of the living dead all around you. All because of that damn T12 virus. You’ll need to complete all the laboratory levels and take down crowds of zombie-monsters. You have the best of American weaponry at your disposal. Choose for yourself how to fight the horde best – with a Deagle or a Shotgun? To survive and save the world from the virus, use both hands and your head. Never stop shooting, pick up rounds, climb up pipes and ladders, jump onto bars and grab hold of ropes, search lockers and throw everything you find at the zombies. You’re free to choose whatever weapons and tactics you want. Prove your agility, imagination and accuracy. The denizens of the Horizon station will punish you for one thing: hesitation...
