A mere couple of weeks after the announcement that Webzen was working on it, the first content update for ASTA: The War of Tears and Winds is now live. This update brings a brand-new Team Arena map titled Ora Fortress Underground Arena, an extra difficulty mode for the current 10-player raid dungeons (Throne of Gladiator in the Four Valleys region and Water God’s Oracle in the Muk Plateau region), and new items, achievements and titles.
Ora Fortress Underground Arena is the newest addition since the Arena of Constellations, offering 5v5 team battles. The process is identical to that of the Arena of Constellations, but a different interior will require players to come up with new strategies.
You can read the full patch notes here. ASTA has entered open beta in March 2, 2016.
