A company press release promises "an exclusive first-look at unseen content with new features being revealed." A public event set in the Black Dagger Ruins will be playable. The event, called Storming the Keep, requires players to join forces and reclaim a fortress that has been overrun by bandits.
Neverwinter was originally designed as a five-player dungeon crawl. Perfect World has since expanded the concept into a full-fledged free-to-play MMO based in Dungeons and Dragons' Forgotten Realms campaign setting.
