Check the tac map to see where they’ve spawned (e.g.: Al Mazrah City, Zarqwa Hydroelectric, Al Samman Cemetery, or Zaya Observatory).

Activating the Altars spawns Zombies that the player must kill until the ritual is complete. Upon activating all the Altars, a portal appears. Enter the portal with lots of explosives and ammo to take on The Butcher and the zombies surrounding him.
