The rules are simple:
- At the start of the week, a number of people are emailed. For a company of about 50 people you could do 4.
- Of the four people, 1 person is emailed to tell them they are infected (zombie). The other three people are emailed to tell them they are doctors.
- The infected person must infect as many people as possible. To do so they tell a person they are infected - that's it. However, if someone overhears them, both people become immune and are out of the game.
- Once you become infected, you can either do nothing, or infect more people. You should email HR with an email 'i'm infected' to let them know you're infected.
- If an infected person tries to infect a doctor, the infected person is now immune and can't infect any more people. They must tell the doctor who infected them. This also goes for if the doctor overhears an infected trying to infect someone.
- Once the doctor gets told of the infector, they must wait until the following day and then approach the infector and ask them who infected them.
- If the original infected gets asked who infected them, or they try to infect a doctor, the game stops. The doctors have found the source of the infection, and thus the cure!
- If the original infector has not been found by end of play friday, the game ends. All doctors are counted infected. All survivors are free to live the rest of their lives in peace, until the following Monday when the game starts again
The score of infected can be put up on a board somewhere, and whoever infects the most people before the end of the game wins a prize (as well as bragging rights)
