You are a group of scientists from other underground laboratories. Your mission is to get into the professor’s laboratory and find the vaccine. But it’s not so simple. His laboratory is a bunker with its own life support system and radiation protection field from a zombie attack. But even if you can get inside, the vaccine is not so easy to find, because the professor has coded his discoveries due to fear of attacks. You will have to go through the entire experimental path again, decipher his logs and codes. It is necessary to work quickly and efficiently, as the system will self-liquidate the bunker in 60 minutes.
