"The AI in this game was very good. Not perfect by any means, but got the job done in a good way. Player's think they have amassed the perfect plan to execute the target, then just like that they find themselves dead at the hands of an enemy sneaking around. The AI will also not back down from a firefight and do a good job of holding their ground. Of course if they see the opportunity the enemies will strafe behind walls, duck, take cover, or dodge your knife in close combat. They will call for backup and when a body is found everyone is alerted and starts looking for a suspicious character, which greatly adds to the suspense."
