As soon as PvP Fights are unlocked by a player, other players in the neighborhood who have also researched Military Tactics may be attacked and the player may be attacked by players in the neighborhood. Any player who has not yet researched Military Tactics is cannot be attacked, because they are unable to have a city defense army. If an attack on another player is successful, that player may be plundered.
This feature is independent of the PvP Arena.
