Anyone registered with FilePlanet or one of its sister services (e.g.: IGN, Direct2Drive) can download the client and get a beta key.
All the keys are gone. Are there anymore elsewhere?
Beta ends today, so it wouldn’t matter much even if there were any keys anywhere.
Closed at request due to beta closing. If you want to start a new, anticipating-release thread, feel free. (Though - by what I’ve heard - you won’t want to.)
