Some more stuff from my experiances only:

- If bots run out of ammo they seem not to pick up a near by gun.

- Bots should try knifing with in a certain distance they pull out their knife sometime but don't attack.

- Bots buy new gun every round

- Try shooting at enemy far away with shotguns

- Accuracy with high recoil weapons gets poor because they hold down trigger and recoil just takes over.

- Bots don't always use scope and when they use sniper rifles such as awp they aim for the feet most of the time.
