Although the game is free to play, there is also going to be a "premium" edition with an install disc and codes for five weapons and some kind of Mag evolution tool.
There's also a new trailer with some gameplay footage. Nothing groundbreaking here, I think, but there are some weapons I haven't noticed in past videos.
You can check andriasang for some more information, a few screen shots, and a nice piece of promo art that is very reminiscent of one for the original Phantasy Star Online. That might make a nice Featured Image to post here sometime soon.
