Me playing on the Japanese version of Alliance of Valiant Arms (also known as A.V.A. Online), a Free2Play FPS that uses the Unreal Engine 3. I didn't even know I had this recording, but thought I would put this up regardless (even though I'm not playing well here, I barely even knew what button to press to pick up a gun at first :P).
Overall, it's a fairly decent game, with some mechanics from Counter-Strike, Call of Duty, and Combat Arms. There's a pretty sturdy learning curve to get over, and for me there's some warp lag at parts, but if you can play any of the above games you can learn this within an hour or so.
