I've been looking this FPS beta over and I think it has potential. Similar game play as BF2 with more stamina controlled movement like jumping and even a forward roll. I ran through a couple training screens and I found the game play smooth and equipment handling responsive. Separate game rooms can be set up on the server for private games or invite only which is cool.
This is a european based game and I don't know where the servers are located but I had good game play with pings of 144 and 160. Check out the web site here and view the WM trailer:
