NCsoft announced the availability of the open beta client for Aion. There are different methods to get the open beta client, the usual and most common via FilePlanet and GamersHell (will be up later this week).
Or via the most popular P2P Network – BitTorrent.
BitTorrent is a legal P2P Network and it is much faster than getting it directly from download sites. If your ISP is blocking you, call them up and tell them the truth about BT. Then download the full open beta client (md5 checksum) or get the torrent patch if you already have the closed beta client.
The open beta will commence on September 6th, featuring version 1.5 of the game catered to the Western culture. It will end on September 13th, and on September 25th European players will be able to play without any restrictions. While North American players will be much earlier on September 22d.
