Runescape - Clan Citadels Trailer
The centrepiece of the Clan Citadels expansion is the clan battlefields, a unique sandbox environment allowing clans to generate their own user-generated gameplay for the first time within RuneScape.
Clans will have access to a full-blown Battleground Editor equipping them with all the tools needed to create and develop their own multiplayer games. Clans can create any gameplay they wish; ranging from simple capture the flag style games to full clan versus clan battles. Once created, clan members can save their games and even invite others to compete in their creation.
