At the Penny Arcade Expo in 2009, Nexon America announced that it would be publishing Dragon Nest in North America. Originally, Dragon Nest was scheduled for a mid-2010 release. Nexon America announced that a playable version of Dragon Nest would be shown at the upcoming E3 show in Los Angeles. Its release is now set to be towards the Summer of 2011. On 21 April 2011, a closed beta application was started and testing was due to begin on 17 May 2011. However, on 6 May, an announcement was made that the closed beta testing would be pushed back to 15 June 2011. Closed beta ended on June 20, 2011. Dragon Nest open beta testing opened on July 26, 2011. The game was slated to go live on August 11, but this date has since been pushed back. The North American version was level-capped at 32 with the Saints Haven release on September 28, 2011. Characters, items and skill from the open beta test were not cleared, so players kept the progress they made in the OBT. In mid December 2011, the North American version has extended its level-cap to 40, giving the player the ability to learn their 2nd sub-class's final skill. The Tinkerer class was added in the June 2012 patch. The first Dragon class nest, Sea Dragon Nest, has been released on 24 July 2012. On 24 October 2012 the North American version extended its level-cap to 50, giving the players the ability to learn their 3rd sub-class. On 20 June 2013 the level-cap of the North American Version was extended to 60, allowing players to learn two EX skills.
