There were a few different gameplay options which included a team work type one - I know that's not what you meant by co-op though, maybe something in the new one?
As for fast paced kill/die/respawn... That's not how I found most of my games. There was the stealth of hiding from the pursuer(s) whilst at the same time sneaking up on your target.
Just running and killing people doesn't win that game. Think I got 8 kills in one game and had many many more points that someone that had got over 20.
