The beta test was available to pre-order customers, and select individuals who had registered earlier. Most players spent the beta trying out different classes, getting to know the game, and contributing to forums. Most beta testers agreed that with the exception of some bugs, the game was well-polished and felt surprisingly finished.
Dev's read the forums and addressed bugs quickly and with candor and humor. While some bugs never seemed to get fixed (poor engineers) others were fixed with patches.
The beta will be re-opened shortly before live release, so that people who cannot get a copy of the game will be able to play. These characters will be transferred to a live server once a retail copy is purchased. It is unclear how long this "extra beta" will last.
