The CS Bots now have an enhanced "attention" system that takes into account gunfire, cover, distance, motion, and posture when determining whether a bot "notices" another player. For instance, previous versions of the bots would always notice an enemy if they had a clear line of sight to them and they were in their field of view, even if that enemy was crouched and hidden half behind a crate hundreds of yards away. The CS Bots notice moving players much more often than stationary players, and the chance of noticing players in their field of view drops further the more cover the enemy is behind and the farther away they are, among other factors. This brings yet another level of strategy to the bot game, making stealth and positioning much more valuable.
