Just started premiering back in October so it's fairly new, and the only warning I can offer about it so far after the first episode is that it follows the storyline of Continuum Shift and Extend decently close, not everything will be the same, but the show follows the tracks of the game very closely, if you don't want the game spoiled, or vice-versa, I would maybe suggest passing on it for awhile till you want to watch it without worrying what effect it will have.
All in all it looks great, I only watched the first episode because I still have some work to do in the game, but here you go: http://www.hulu.com/watch/545312

I'll find it on anime box when I feel like it
