Guild Wars II Twilight Assault update revealed

ArenaNet today announced Twilight Assault, the newest content update for massively multiplayer online role-playing game Guild Wars II, launching on October 1.

The developer said the update "continues ArenaNet's commitment" to releasing new content for players every two weeks, a rate it claims is faster than any other Western competitor.

"In Twilight Assault, trouble is stirring in Twilight Arbor and rumors abound that Scarlet Briar, the devious leader of the Aetherblades, is behind the suspicious activity," reads a line from the content's description. "Players will join the sylvari hero Caithe in attempting to stop Scarlet's scheming, but it will take daring, wits, and weaponry to put an end to the mischief."

Twilight Assault also features a new level 80 path in Twilight Arbor where players can work together to find a way into a hidden facility where they will battle guards and monsters.

New rewards offered in the update include the Slickpack back item and new versions of the Nightmare weapons. In addition, players can collect Aether Key Pieces from across Tyria and combine all five to form a key that will open Aether Chests in Twilight Arbor.

Gamers can get an early look at Twilight Assault during a preview livestream with ArenaNet developers on Monday, September 30 at 12 noon PDT through Twitch.

Finally, ArenaNet also announced today that the next Guild Wars II free trial weekend will take place Friday, September 27 through Thursday, October 3.

Guild Wars II launched in August 2012 and has sold over 3.5 million copies to date. It is the fastest-selling Western MMO ever, according to data from research company DFC Intelligence. The game's playerbase is expected to grow substantially when it is released in China.
