WAR's new city sieges now have a maximum battle time of two hours, feature a respectable 24v24 population, and offer plenty of rewards, including a PQ-style chest roll for the winners. Once a player joins the fray, they'll be automatically put into a warband and pointed toward the battle.
City sieges take place over three stages, each with specific objectives and a time limit. In stage one, the invaders will attempt to breach the palace gates while the defenders try to stave them off. This is accomplished on both sides by waging war over linked control points that function as a tug-of-war between the forces. Moving on to the second stage, each side has the win condition of either escorting their warlord to the palace gate or defeating the enemy warlord. Depending on how stage two ends, stage three will take place either in the palace or at the city's gates, and involves killing the enemy's king. One of the neatest parts of this final stage is that four players on each side will be chosen to be "Champions" -- highly buffed characters with a special new ability.
The new city sieges sound streamlined, dynamic and -- dare we say it? -- a bloody good time for all. You can check out the proposed development notes for this patch on WAR's forums.
