Perfect World Entertainment has announced that Forsaken World closed beta 4 is now live.
"This phase marks the opening of the floodgates to anyone that wants to get their hands on Forsaken World before the full launch of the game. This means that you and all of your friends, regardless of whether a beta key has been redeemed, can test out Forsaken World during this phase!"
One of the biggest changes with phase 4 is the new PvE server and the implementation of the auction house system.
