Core Ruleset
Standard game mechanics. RvR combat between players will be limited to RvR areas. Players will be able to flag themselves to fight enemy players in their own PvE areas if they wish and will automatically be flagged in enemy-controlled PvE areas.
Open RvR
Players will be able to engage in RvR combat just about anywhere in the game world if they wish, with no need to flag or for others to be flagged to attack them.
Roleplay
Players will be expected to follow additional rules governing character naming and in-character speech. They must essentially roleplay - act as if their character was a real character in the Warhammer World - as much as possible. Roleplay servers will follow the Core ruleset.
