We've all had a good share of incompetance in the AI of non-player characters, either from a quirk or mishape in their workings or from bad programming alltogether, and while most of the time it can fracture or outright sodden the game's immersion, sometimes they'll throw an utterly ridiculous scinerio that's so downright funny you'll want to pay more attention to it than continue with what the game would normally want you to do. If you've ever had such a situation, share with us one of your stories involving or the result of bad AI decisions.


I'll start off with one I had recently. The game which provided the experience was Fallout: New Vegas. You'd think all the humor and glitches it has would be enough for the poor game, but now the AI had to get in on the quirkiness of Fallout..

I was following down one of the rivers of Zion Canyon, one of New Vegas' DLC locations, with all but the moon's reflection as the only source of light, when two tribals in red and white war paint jumped down from a rock ledge to the right to attack. Both were using close ranged weapons. I took the first one down easy from a burst of my snazzy laser-spitting tommy gun. In that short time the second attacker had decided to go for my NPC partner, a bald tribal girl who used a bear claw for a weapon. Normally she's able to take care of herself, so I put away my gun and helped myself to the first guy's valuable tomahawks to sell for later, to which I'd then wait for my partner to take down the second and repeat the same process on. But what happened when I turned around to see them?

They were both cuddling in the water.

Yes, cuddling.

If you've played Fallout 3 or New Vegas, you'll remember that they're one of those games where you can't use your weapons in the water, and all you can do is watching your player loop through his or her swimming animations until you've made it back onto a traversable surface. Even though my battle first took place on dry land away from any wetness, my partner must have strafed into the river while I was gunning down the first attacker like a retro-futuristic gangster Stormtrooper from the 1920's, and the second attacker jumped in with her.

But the bloody battle-to-the-death the game had set up did not go as it had predicted, however, as the two had fallen in love so swiftly and so significantly that the two tribal warriors, both taken pleasure in the sight of their enemy's blood, decided to instead take pleasure in each other and immediately sheathed their tribial rivlaries without question or any hint of a second thought to lovingly embrace in the water, throwing their wet painted arms around each other in the gleaming moonlight. It would've been the perfect moment of romance in New Vegas, had the two decided to cease spouting battle threats at one another. "Yield!" shouted the girl in all her sharp seriousness. "Un niyaway wichoo." replied the tribal dryly. Either old habits die hard for the local tribes or that was tribal talk for "I love you, girl".

This went on for a good three minutes, with me just standing there watching, wondering if inside that stern and intimidating NCR ranger helmet my character was all sweaty and eager with sick anticipation, hoping for some in-water Tasmanian devil-like scene of passion that she'd get to watch and pleasure herself to like the Vegas sleezeball she was.

Two seconds later?

The game crashed.

Yes, apparently the game, so prideful in it's masculine laser battles, was so ashamed of the hanky-panky scene it had created that it committed Japanese ritual suicide on the spot and threw me back to my Windows desktop, depicting a Garry's Mod screenshot of Ellis from Left 4 Dead 2, high enough on adrenniline that he was running through the loop-de-loops of the Green Hill Zone.

Fortunately I had quick-saved during their affair. I guess I had the same sick desire as my character and wanted to make sure some post-apacolyptic loving was assured. And when I loaded the game back up, not only were they still together in the water...

...but my partner was now underwater, with her arms around his waist.

I don't think I need to go into too much detail about what was happening..you'd think the tribal chiefs, with one being an intelligent white man, would've taught these people about howfirst, second and third base work. But no, there she was, underwater like some sort of aboriginal hooker at work. And if you don't think it gets any weirder...she drowned. Within the minute she was floating lifelessly on the water's surface. Yeah, I had no idea NPC's in Fallout could drown, but she did. Then next thing I know I'm getting pounded on by the tribal's bladed gaunlet as if everything was my fault or he was expecting my character to take over for my now-deceased partner, and was beating on me for not putting out fast enough. Mostly due to the immense laughter I was encased in, I died before I could retaliate. Weird way to go, but I wouldn't doubt if weirder has happened in Vegas..

That's my story, and I'll likely share another later on. Until then, is there any story of AI mishaps you can share?

nothing...quite like that, but ive had a few experience with wonky AI in crysis 2 recently (im going through my backlog of games).

one mission where it is...recommended to stealth past the enemies. after going through a cloak->sprint->hide->recharge cloak->repeat cycle moving past the enemies patrols in burned out buildings, suddenly from distance behind me:

?: AAAIIEEEEEEEE!

me: (scanning behind me) what the hell?

(THUD!) an enemy sniper patroling a lighthouse FELL TO HIS DEATH ON HIS OWN.

enemy patrol: (seeing the body) we have an intruder!

ALARM ALARM ALARM

me:..................

sadly this happened a few times when i reloaded. Sometimes the sniper will fall to death, sometimes a patrol will fall out of the destroyed buildings they are exploring. each time the alarm sounds, even when im hundreds of feet away.

I absolutely COULD NOT get passed the second chapter of the "Dead Air" campaign in L4D (called "The Crane," and also note I was playing this single player with the other 3 characters run by AI). Basically, you're on a rooftop and there's this crane you've got to activate to get to the safehouse, and as soon as you activate the slow moving thing you've got to defend yourself from a huge wave of zombies as it does its thing. The problem I had was I would hop out of the window down to the roof, activate the crane, then as soon as the wave hit all three of them would fall off the fucking roof. Seriously. I would even hop down, wait for them to all safely get onto the roof with me, then activate it. Every single time they would all be dangling off the edge and asking for help within an instant. I couldn't understand it. I couldn't even figure out when they were falling off the roof, it was as though as soon as the monsters turned the corner they all just fell off. It was so ridiculous I finally skipped the stupid chapter.

Also, in HL1, there is one part where you come across a room full of unarmed scientists and you have to safely guide one of them through several dangerous corridors so they can open up a passcode-locked door for you. The problem is, when you're near scientists with a gun out, they get all scared and run away from you. I didn't realize I was coming across a room full of scientists, so when I opened the door I had a gun out. So all of them went crazy scared as soon as the door opened, and they instantly went running and screaming into a wall of spinning blades. And naturally that was an autosave point so I couldn't go back and re-open the door with something else out.

So I spent probably 45 minutes herding a terrified scientist around a labyrinthine lab wing, circling him around again and again until finally I circled him close enough to the passcode panel that his AI instruction to open it kicked in. It should have been easy--shoot everything that gets in your way as the scientist calmly follows you to the door. But noooooooo. I went from Gordon Freeman: Savior of Black Mesa to Gordon Freeman: Manic Scientist Herder.

My friend once experienced a glitch in minecraft terrain generation where he came across this huge cube of about 5000 blocks of water just hanging in mid-air. So naturally, he decided to get a bit closer to the anomaly, at which point each block turned into a pig and caused the game to grind to a halt, corrupting his save file.

My worst is probably playing as a Vampire in Oblivion with dialogue - I'd complete a quest for someone, they'd give a heartfelt thank you, saying they'd always be a friend, then two seconds later they'd tell me to get lost.

This is from another thread:

ChromaticWolfen said:
Oblivion, I will set the scene. My Orc character was causally walking through the Imperial City when I was attacked by those Mythic Dawn assassins. That part is obliviously scripted. What happened next is the best thing. Two guards attack the assassin with broadswords and begin killing him. After a few swings the assassin is dead but one guard swiped his sword one more time and hit the other guard. For some odd reason the guard must have thought the other guard was attacking him so he fought back. Soon enough it turned into a street brawl were over 12 guards were fighting each other, 6 on each side. After about 10 minutes of fighting on side eventually won with one guard left alive. The best thing was that after the fight the one guard left looks around and says "Theres been a murder here". Never laughed so hard.

Left 4 Dead 2: During the no mercy remake, the whole enemy team, including a witch ran clean off a skyscraper. I have no idea what possesed them to do it, all I know is that I have never laughed so hard at an AI before that moment (The best part is that the hunter that fell was actually shot to death by Louis before it died from the fall.).

While romping around in Skyrim, I found many A.I. hiccups, some funny while others were, well....

One time I was heading up to Bleakfalls Barrow to get the Dragon stone, and got to the bandit tower stealthy as possible, and then I get detected. Bandits start shouting warnings, weapons drawing, the whole nine yards. Turns out that it wasn't for me, because apparently a rabbit ran by and tripped their alarm, prompting all three of them to chase it up the mountain.

A similar thing happened with a dragon while out in the wilderness. There I was, firing off every slightly pointed stick at it that I could in hopes to kill it, and it just flies off a ways and attacks something. It then takes off and I run to where it was to find, low and behold, it was a fox.

Another time while facing a dragon near the wall by Dagon's shrine it literally got stuck in the ground, immobile, for about three minutes.

Though the most fun that I ever had with an A.I. was in Red Faction: Guerrilla, to be more specific this always happened in the beginning of a guerrilla assault. I'd get either a pick-up or a pick-up van, load it with the people near by who were going to the same place, drive over to the site, and run the vehicle as far into the building as possible. Good times, good times.

when time while playing command and conquer 3, i went to capture tib spike, and did so with a rifle squad to back them up. i set them squad in a foxhole and left to do other things.

10 mins later, i wonder why i'm not being attacked.

i look to see the entire enemy army centered around that one foxhole, men, tanks, planes, everything.

doing nothing. they were still cranking out units and piling them in to the mess. it was much lol. they didn't fight back when i attacked them, either.

SO poetic! that had it all, Violence, sex, tragedy, humour. haha, great post.

OT: None really spring to mind, Apart from in the original prototype where you'd land a helicopter in full military disguise, and a passing tank wants to kill a single zombie with a freaking shell to the face. giving the zombie serious plastic surgery and blowing up my hard earned helicopter. I soon learnt not to land 'copters in the road.

Going back to 2000, Hogs of War. The AI on one level decided that bazookas were for wusses and that bare-trotter boxing was the way for the manly hog to go. My guys disagreed and blew them to kingdom come.

Coding AI is probably the most difficult part of coding really. Mine would be my top-down shooter project where no matter how much I tried to get the enemies to go around walls they just couldn't. This is why I don't feel angry is the AI goes wrong like say a unit getting stuck on a wall because I know how painful it is to try to figure out and fix what's going on.

Once when I was play Fallout New Vegas I was standing outside the bunker where you go to get the enclave power armor from Arcade Ganon's Dad's old Enclave friends. I had heard that having Rex in the bunker may crash the game so I told him to go back to the lucky 38 with quite a few weapons I give him to hold onto including my Euclid C finder and anti material rifle. So after getting my armor I head backto the lucky 38 and see that Rex is no where to be seen, I thought he might have died some where in the wasteland on the way back. Then about two months later I decided to give the King a vist for some reason and as I leave his hideout I see Rex sprinting gowards the strip, I followed him trying to catch up but eventually he went straight into the lucky 38 and went up to my room. To this day I have to idea how it happened but I am happy that it did.

Seven years ago I was fed up with humanity and decided to create Skynet, it wrote "Hello world!" in the command prompt.

The Brink AI. Damn I hate that AI, can't get past a level because the AI "adjusts with you". Meaning your allies don't attempt objectives and won't cover you if you attempt the objective.
The enemy team AI on the other hand start becoming really cheap too. I know that it's mainly a multiplayer game, but still. Still, my only complaint is that the AI might as well run around in circles for all the good they're doing.

Many times in Saints Roy games, the cops will end up killing people while I just stand there, perfectly still. Actually, alot of things happen in games like this. Take Destroy All Humans 2, for instance. Had a case where I had to do the last mission to defend hippie communes against...EVERYBODY available in Japan, which is nearly all the enemies accummulated at once. Thing is...you can fake-out the AI into believing nothing's going on by physically preventing them from getting to your area and thus they can't see you, especially if the alarm rate's been called off or they've neded up fighting each other.

I have a couple stories that I can't recall. But I'll mention the ones that stand out to me the most.

Not sure if this counts (cause it wasn't as much stupid AI as it was AI making a equally bad decision from what was available) but in the first Halo, I threw a grenade towards an elite on the edge of a platform. Instead of talking the grenade like a man, he proceeded to roll off the side of the platform and fall to his death.

In SWAT4....I don't need to elaborate, the game is fun, but watch any video on youtube and you will find some very incompetent SWAT officers. "You're in my spot sir."

Halo and driving, a story of hilarity and tragedy.

Halo 1 - they AI can't drive, only use the mounted guns.
Halo 2 - at last they can drive!.............around in circles and go nowhere
Halo 3 - they can drive at the enemy at least....let's hope they take the hint when you run out of rockets.
