The closed beta client for Aion has been released today. So, for those of who you have pre-ordered or pre-purchased the game, it would be a good idea to get this thing downloaded as it comes in at a hefty 6.11 GB.

Pre-orders will be able to enter the remaining closed beta events, which are scheduled for July 31st and August 14th 2009.

The closed beta client is available at GamersHell.
