How a match works
SummaryAt the start of each match, players are split into humans and zombies. The round runs through six waves, and the outcome depends entirely on which team completes its goal first.
- Humans survive all six waves without every player being infected
- Zombies infect every human before the sixth wave ends
- Zombies respawn after being defeated and keep attacking until the wave closes
- Team check which side you are on as soon as the match begins

Common questions
FAQDo humans win if they are still alive when the sixth wave ends?
Yes. The human team's goal is to survive all six waves. As long as at least one human has not been infected when the final wave closes, the humans win.
Can zombies keep respawning forever?
Zombies respawn after being defeated and can return to the fight as many times as needed. The only things that stop them are the wave ending or every human being infected.
What do pro servers change?
Pro servers become available once you have earned 50 or more wins.
