One step closer to Judgement Day
It's tough to argue that games haven't gotten better over the years. They look better, they play better, and, most importantly, games are smarter. Early AI were simple goombas that walked into bottomless pits, but that has advanced as far as games like FEAR (which has some of the best enemy AI in a shooter). Recently, the Alien: Isolation developers started showing off their upcoming game's amazing living, breathing alien that's said to hunt and react to players' play styles. Or, at least that's what they're saying now. The thing is, sometimes developers exaggerate and inflate their tech's capabilities, ultimately leading to a disappointing AI showing in the end product.
Evolving combat through AI (Halo Combat Evolved)
You can't talk about the advancements in gaming AI without bringing up the enemy intelligence in the original Halo. It might be common now, but before Halo: Combat Evolved released, gamers weren't exactly used to enemies taking cover, dodging grenades, and generally using their brains to kick their ass. Pre-release, the developers claimed they had something special in Halo's AI. I mean, it was right in the title: Combat Evolved.
The smartest NPC crowds ever (Assassin's Creed)
The original Assassin's Creed did some crazy stuff. You got to explore massive cities, climb any building you could see, and hide yourself within a crowd of NPCs. That's the AC we all remember anyway, but before the game actually came out, Ubisoft had some lofty AI promises. The developers even went so far as to say in early interviews that NPCs who saw Altair murder a guard with his hidden blades would remember the assassin days later if they crossed paths again. They'd even pick Altair out of the crowd yelling, "Hey, Assassin!" or something.
AI enemies that use combat tactics (F.E.A.R.)
Halo might have gotten us used to smarter enemies in our shooters, but the developers of FEAR decided they wanted to take their game's AI to the next level. The enemies you face in FEAR are supposed to be special forces badasses, so if they acted like idiots it wouldn't be very fun. So, developer Monolith said in interviews that the enemies would be smart--very smart. They'd take cover, work as a team, throw grenades at you, and do everything you'd think a special ops team would do to try to kill you.
Smarter enemies in a stealth game (Splinter Cell: Conviction)
The thing about taking on enemies in stealth games is that every bad guy you run into is blind, deaf, and dumb as a post. Seriously, sometimes you can be standing right beside them (albeit in the dark) and they would have no idea you were there. With Splinter Cell: Conviction, the developers said that wouldn't be the case. Instead, enemies would spot you, hunt you down, and kill the crap out of you if you didn't stay on your stealthy (tip?) toes.
A companion that doesn't screw everything up (Bioshock Infinite)
I wasn't all that excited when I found out Bioshock: Infinite's Booker would be followed at all times by an AI companion. Traditionally, companion AI never felt right and was a bit of a pain. But the developers said the supernaturally gifted Elizabeth would help Booker through Columbia. She'd toss him ammo, use her powers to open portals, and would never get in the way of the action. They were confident the AI would hold up to gamer's expectations, but I would be lying if I said I didn't expect Elizabeth's potentially wonkey AI to screw up the new Bioshock--at least a little.
Hyper-intelligent fish AI (Call of Duty Ghosts)
Because the Call of Duty franchise releases a title once a year, sometimes it seems the developers stretch it a bit to highlight the improvements from one year to the next. In building the hype for the latest entry Ghosts, Infinity Ward decided to show off the intelligence of the fish players would encounter in the very first Call of Duty deep sea diving level. Apparently the fish had super advanced, individual AI that had them scurrying away from players as the gun-toting soldiers passed by.
Game AI in the future (Middle-Earth: Shadow of Mordor and Alien Isolation)
And so the look to the past brings us to the now. There are a few games on the horizon toting their game's artificial intelligence prowess--one of those being Middle Earth: Shadow of Mordor, promising persistent enemy AI. That means, if you fail an assassination attempt, your victim remembers how much of jerk you are later on in the game. Whether that translates to your enemies being better prepared next time, hunting you down to get revenge, or simply spouting a few extra lines of dialogue about how you burnt their face off is yet to be seen. The developers have some big promises to live up to.
