On this gamemode you will spawn on a closing server with 39 other players(totally 40 people) and you will fight for surviving. If you get killed, you can watch what is happening on spectate or go to another server. You can't respawn. After there are less than 20 people on the server, pellets on the map will increase for about 68,27%. When there are less than 10 people on server, leaderboard will start decreasing (showing only 9 places, then 8places...) and when there is only 1 player left, he would have 15 minutes to do some funny things, or change server.
