I only got to play a little of this so far, but I liked a lot of what I played. Unfortunately it did make me a bit nauseous/motion sick after. I tried enabling the crosshair and I turned on the "anti-motion sick" switch (no idea what that does but cool that there is one). I think I need to slow down the mouse look some more. It's been a while since an FPS got me dizzy, I'm not sure why this one in particular had any effect, it could be because I'm still getting over a cold.
My only complaint so far was that in the match i joined, they threw me in at the end and it was a pretty high level group fighting a boss. I died in about a minute and spent the rest of the time watching. Surprised there isn't any kind of respond or method to bring players back? I went back and played some more solo which was still pretty fun. I can imagine if I got the right video settings and into a more suitable group it could be a lot of fun.
