How it plays
Everyone starts as a survivor. After 12 seconds one player turns into a zombie: knife only, but faster, with far more health and harder hits. Anyone they cut down becomes a zombie too.
Survivors have to last until the round ends (2.5 minutes). If everyone gets infected, the zombies win. It is played on almost 30 maps.
Tips
- Pick a spot that can only be reached from one direction.
- As a zombie, rush together with the others.
- Zombies take a lot of hits, so start shooting while they approach.
Solo or with friends
You can play it alone at any time: if there are not enough people, bots fill the match (up to 10 players), with skill from easy to pro. It is best with friends in a private room: you get a 4-letter code and a link, your friends join with one click, and you choose the map, the number of bots and their skill.
