i know how but i cant power level. All you basically do is taking turn killing who ever's the infected.
Player 1 and 2 are get Host Infected.
So player 3 and 4 get to kill player 1 and 2
but if you kill them right away in the end it'll count as abnormal game play.
So what i do with my friends are wait till 2:00 to begin killing the infected
Then you just keep repeating
