Free-for-fall and team free-for-all game modes have been added to the game along with a new map, "The White Walls of Calderis". Additionally, plays can now vote on preferred maps for matchmaking, which will be fed into the system and attempt to match players on his or her preferred maps.
A host of balance changes have also been introduced as well as improvements to the garrisoning and transporting systems. The patch should be automatically applied through Steam and the full notes can be found below.
