Infected [The Infection]

In 2019, humanity was hit by a terrible epidemic. The mutation of an old virus makes its victims bloodthirsty zombies. You were called to carry out this mission because, a few days ago, Professor Anton Radkevich announced with a walkie-talkie that he had synthesized a vaccine to cure the virus. After that communication, however, contact with the professor was lost. Central Bunker has called your team to find out what happened, but the most important thing is to get the vaccine back.
