The research center conducted experiments on people, which led to terrible consequences. Some of them mutated and turned into walking dead. One bite started a chain of transformations and in a few hours the whole laboratory, except for one guard became a zombie. Armed with a pistol, he must enter the vault and destroy all the data on the experiment, and then get out of this hell. Monsters will attack the hero almost every corner, be careful and beware of those who are picked up from behind. Watch the level of lives and cartridges, look for new weapons that will help you survive in a difficult situation.
