I picked it up along with the BT headset from some in FS/FT, so I'll do a quick thread resurrection.
I'm not very impressed with the game. I was kind of expecting a bit more thinking, a little bit less run-and-gunning. But the maps are so damn huge (or at least seem that way) that it seems like the game basically devolves into "who runs into the back of whom first" - or into a giant camp-fest in some cases. Maybe this will get a little better when I get better at the game, but it really seemed like the maps were a bit too complicated for their own good. (FWIW, my last experience at a "tactical shooter" was plain old Counter-Strike, where I was pretty decent.)
Technically, though, the game seems fairly solid. No latency issues I could see, and framerate seemed pretty steady.
