AI is usually a key part of shooters, you see it in the Call of Duty franchise, Battlefield, Tom Clancy's game and thousands, if not millions more. There isn't an exception for top-downs. Right now, there is only basic aim, detection and shooting for the AI, but that will change, if the AI sees you, it will approach your last location, it'll patrol areas, and will use aiming prediction so it doesn't fire right at you, but in front of you. Hoping to release the update in November.
