Quest House: Infected

 In 2019, humanity has been hit by a terrible epidemic. The mutation of an old virus is turning its victims into bloodthirsty zombies. You have been asked to carry out this mission because, a few days ago, Professor Anton Radkevich announced via walkie-talkie that he had synthesised a vaccine to cure the virus. After that announcement, however, contact with the professor was lost. The Central Bunker has summoned your team to find out what happened, but the most important thing is surely to recover the vaccine.
