Each game must have at minimum 40 players. Every player is transported to a city, either the lumbridge, varrock, or RS gold seer's village. The players must all defend their home until they've been able to defeat all zombies. they will all come in waves, with each one becoming more difficult, the final waves is wave 5. after they have overcome waves 5 and 6, they will be transported by the spirits of deceased warriors who died trying to defeat the zombies to falador, from where they will meet with teams from other cities. The first task is to overcome "the Hive" which is a giant gooey egg-like shape, it shoots horrendous gunk at players. Once they've defeated it an enormous boss zombie pops out of it. The game is at level 400 and grows to 20 levels for every player left on the field.
After you've defeated all the boss zombies corrupt points are gained that can be utilized for prizes in the minigame. The prizes include the Rod of Darkness, which is a powerful staff that takes three quarters of your health, and OSRS buy gold causes damage of 25 to those within 5 inches of it (note that this effect only occurs only if your health is kept up).
