I played tens of thousands of hours of this fast paced FPS... If you're looking for something new to play, this might be it.
12 years ago, the original came out and its still one of the most played games online daily.
I'd give you more a gameplay review, but I'm downloading it myself as we speak...
And only $15 to boot!
