An icon will appear on player's screen. A letter will appear on the player's screen, this letter is the player's identity.
Press A+B to start the infection game. The master will pick a random player as patient zero. Once all your players are registered, press `A+B` to start the infection game.
The game will pick a random player as **patient zero**.
A player will transmit the disease if close enough (RSSI) and with a certain probability (TRANSMISSIONPROB). A player will transmit the disease if close enough (`RSSI`) and with a certain probability (`TRANSMISSIONPROB`).
During the incudation phase (INCUBATION), the player does not show any sign of illness (happy face). During the incudation phase (`INCUBATION`), the player does not show any sign of illness (happy face).
After that phase, the sad face shows up. After that phase, the player gets sick and shows a sad face on the screen. After the sick face, the player dies and a skull shows up.
