My friend and I actually just played a round of Black Ops, us against eight veteran-level bots. The thing about veteran-level bots is that if they're facing in your general direction, no matter where they are in space, they will almost certainly kill you. And there's eight of them, against us two, who almost never go online.
It was the most fun I've had in a while. We had to hide in a building with only one entrance, and one of us would lie flat on the ground aiming at the stairs while the other one would fire at the very few bots that didn't notice us below on the street. They called mortars in on us about five times and about every five minutes, a semtex would fly in and kill us, destroying our tactical spawnpoints and throwing us out onto the street. We had to make a mad dash back to the building then. Eventually, we figured out the perfect strategy: one of us aggros enemies by throwing grenades or shooting haphazardly out the window, at which point the bots immediately know where we are and start coming after us. One of us is at the top of the stairs facing the wall with a suppressed shotgun, and when they come up the stairs, we shoot them in the legs and instantly kill them. We won by four kills in a round with a goal of 150 kills.
Imagine doing that with players. It would be impossible. They function too differently for anything like that to work.
