GamesRadar writes: "As game makers can probably attest, one of the biggest challenges of creating a good first-person shooter is the artificial intelligence development. Programming an AI-controlled bot to perform with enough skill and unpredictability to convince you it's a real opponent is a tremendous feat. In fact, I don't believe any modern shooter has produced artificial intelligence that would pass the Turing Test (a thought experiment where a computer persuades a test subject that it is human). Even with the relatively advanced AI in games like F.E.A.R. and Crysis, at no point during those gameplay experiences was I fooled into believing that the enemy soldiers I mowed down were anything more than automatons navigating a scripted path with limited awareness of the environment."
