-the bots are not stupid
-the hold back and wait for you to do the objective, even say for example a bot soldier is at the objective he will not complete it in the first few minutes.
-they get more intelligent and aggressive as the time ticks down and they realise your aren't going to get the object done
-they act more intelligent when there is more humans on the opposite team.
Well the bots are certainly not intelligent. The only - more or less - intelligent AI I've seen in a game is the one used in F.E.A.R.
I loved those bots because they were taking cover and try to outsmart you to kill you from behind at times.
Dunno if they actually hold back. But they do wait for you if you're a medic, which often makes more sense than joining the respawn wave. One could argue that this makes them more intelligent than most players in this regard.
They don't get more intelligent, they just use (or exploit) more game-mechanics. This makes them really similar to the Counter-Strike Source bots. On easy settings, they're plain stupid. On hardest settings they soundwh-re you across the map and will headshot you once you step around the corner.
Same goes for the BRINK bots. I wonder if Silent Running will make them as stupid as CSS bots when you walk in that game.
Maybe their amazing reactions can be slowed a bit in turn for being smarter...
This would definately make sense. It's just unnatural how fast they turn around and down you after you snuck up on them and open fire.
Using a silencer leaves them completely clueless, though, it seems.
