Game Idea Repost

I had a thought when I was reading a blog for Game Design; if anyone can think of any games like this, let me know because now I want to play one:

"What if... we took fighting games and FPS's and smashed them together? Are there any games that do that? I wonder if you could keep some of the combo-based dynamics of 1v1 fighting games and apply them to a larger multiplayer setting. For example: what if you were playing a classic FPS game like Capture the Flag or Control point except that instead of using shooting combat, you encouraged some sort of hand-to-hand dueling atmosphere with some stealth thrown in? This probably already exists somewhere but it could be an interesting way to take a fresh look at fighting games."
