For our first Beta Weekend Event (April 27-29), home-world selection and world transfers will work just as they will when Guild Wars 2 launches.

When you log in to the game for the first time, you will have the opportunity to pick any available server, or home world. If you choose to select a home world that is in a different region from where you purchased your game, you will be logged out for a short period of time while your account is moved to your new region. Once you have selected a home world, all the characters you create will play on this world and will represent it in our world-versus-world (WvW) format.

While you can change your home world, there is a limit of one world transfer every seven days per account and a charge of 1,800 gems for each transfer. A world transfer moves all of your existing characters to your new home world. Any subsequent characters you create will also play in this new home world.

When Guild Wars 2 launches, you will also have the option to play with your friends on another world with our free “guesting” feature. With guesting, your characters can play on any world where you have friends—with certain restrictions. For instance, you will not be able to participate in WvW while guesting.

While home-world selection and world transfers will be available during our Beta Weekend Event, guesting is not currently available. All players will be able to receive 2,000 gems free for the Beta Weekend Event, so you will be able to purchase a world transfer if you find yourself in need of one. Since the limit is one transfer every seven days, you’ll only be able to change worlds once during the Beta Weekend Event.

We strongly recommend that you plan ahead and choose your server before the event begins on April 27.
