F.E.A.R. has been around for 20 years now. It was released on 18th October of 2005 for Windows and later on consoles. I played it around a decade after its release because of the rave reviews regarding its game AI. There were video essays and rankings on why F.E.A.R. has the best AI among all the games. After playing the game for few hours, I could agree with what

I have only played the originals + expansion packs. I did not even finish Perseus Mandate. The AI was not some incredibly complex system. It was a due to incredibly clever design that players could redo the same encounter repeatedly and get different outcomes. Jeff Orkin was the senior AI engineer for F.E.A.R. He did a master's degree in 2007 and a PhD in 2013, focusing on artificial intelligence research from MIT. This should not come across as a surprise.

Gameplay Handled by 4 Programmers

Among these, Jeff Orkin was the one handling the AI. Others did a phenomenal job to keep rest of the gameplay at a highly polished level. You can play F.E.A.R. today bought at dirt cheap prices and have a great time. You can use almost any cheap laptop you can find and have an excellent gameplay experience.
