I wasn't very impressed by the AI at times

I shot the petrol tank on a humvee and it set on fire, then the koren guy standing by it decided to get in and try to drive off. As funny as i found it, it kinda... sucked XD

F.E.A.R. on the other hand, has some of the best AI i have seen in a game. Can't wait for teh new one

Don't like the look of AC, but i shall get my hands on it when its released for pc im sure

The ai is subpar because of dynamic pathfinding and the huge range of environments.  You cant have insane graphics, physics and perfect ai at the same time, especially in a sandbox game.  I personally think the ai is far better than far cry's.

You can't compare FEAR's AI to Crysis. In Crysis you have an open environment where the AI has to interpret every object and cover available dynamically in an open world. In FEAR you are in a closed office setting where enemies are limited to just corners and office windows for cover. FEAR's AI was much easier to implement compared to the sandbox type in Crysis.

Personally, I loved the AI in Crysis despite the bugs. They try to flank you and dodge for cover when the situation becomes too much for them. The also don't see you behind bushes and other objects. Vegetation plays a role in this game. In addition when you are cloaked they keep firing at the position they felt that you were last. If you are clocked and go into a brush and move around they hear you and move on your new position. Also, if they have flashlights or you go up to them while cloaked in full daylight they squint and notice you.

However, when you take over a boat the gunner does not react. Sometimes when you  blow up a car they become confused, and other times different cover objects and situations can be confusing to them, but ultimately I think Crytek pulled it off pretty well.

i didnt have any problem with AI , i think it was very good

They said they had alot more ideas for AI; but they were limited because they had only started working with the new animation system; and they weren't able to develop them side by side.

Expect the AI in Crysis 2 to be the AI we've been looking for in a game.

i Find the most annoying thing about the ai is thier aim...the appear, on delta, to have no recoil and no spread. and ontop of that they fire almost instataniously upon seeing you, and they are always facing you when alerted. what makes it worse is that they spot you from 200 meter's away in bushes...and when u duck for cover more often than not this will sumhow not effect thier vision and theyll continue firing. This makes things hard in a "not fun" kind of way...the ai used for the little aliens is awsome, constant flanking, hiding, flying up/down/gripping walls, hiding. no complaints there

The AI definitely needs some fine tuning.

Crysis has the best (yes notice the word best) sandbox based AI. and as a previous poster said: you can't compare it with games that are not sandbox (FEAR)
if there were a prefect AI it would crush your cpu. like a.. i don't know but something that can crush things with awesome power...

Sadly, AI are pretty dumb in Crysis compared to say, GRAW2..

The A.I. was OK the first time I played Crysis. OK because I didnt care much about it and its glitches I was just impressed by the whole experience the game gave me. But now ...

Okay, its sandbox. Okay, the A.I. has to handle the enviroment, has to find routes and so one. I know that you can't compare it with the FEAR A.I. which always felt pretty scripted to me btw, not very far from the typical CoD A.I. Clean Indoor Levels are pretty easy for an A.I. especially because their routes are mostly predefined and fine tuned with handcraft which helps a ton to make them look smart. In vaste outdoor levels like in Crysis you simple can't tune it this way, it won't work well and cost several hours of work.

I like to play Crysis from time to time again and again. I pick one of the first 5 maps with a lot of enemies and try to figth them in different ways, find new routes, all that stuff. But every time I do this Ive to say that the A.I. annoys more and more:

1. They get way to much confused about bullets hitting rocks etc around them. So they turn around very often even if you are cleary in their view. Only if you make more noise then your own bullets it gets better.

2. Cloaking device. I must say I hate it now. It moves a ton of suspense out of the game. Stuff like taking cover, reaching targets while trying to keep covered and so on. Just cloak and walk to the next bush, reload energy, walk, reload energy, walk. Pretty effective to avoid masses of enemies without _any risk_. Way to effective, thus plain boring.
So I tried to NOT use cloak. And guess what happend? I found out the A.I. has eagly eyes - you're just doomed if you try it even in the "jungle", the A.I. is just uber. Without cloak you're like a BIG RED MARK to them, if they see one pixel of you they know exactly where you are, sometimes even from absurd ranges. Fighting in the jungle is a pretty tough thing - did you see just a shadow or the enemy? The A.I. is never confused - if a tiny bit of you is visible - they know exactly it's you, and not a moving shadow, even not one of their own comrades. You. _Artificial_ is just the word that becomes a bad taste here. It feels completly unnatural and unfair.

Not that I actually DO understand that the way the A.I. "see's things" is pretty different then from the player. I guess those bushes and trees and stuff are just vis-blocking boxes for the A.I. and if they don't cover you 100% the A.I. shoots. In this way Crysis forces you to use cloak - which, on the other side, makes it to easy again. In other games, like Far Cry, it isn't necessary to be 100% covered, the A.I. is less sensitive and gives you a fairer chance. So its not just that cloak makes it to easy to hide, it also makes it almost impossible to hide without it. And that's why I don't like it, the idea of cloaking gives me the choice between having a ton of enemies shooting around or beeing bored.

3. Aiming. A thing that's typical for a lot of games - because the A.I. can't be as clever as a player it needs some advantage otherwise and that's mostly aiming. But in Crysis it gets a bit absurd. I'm supposed to be some Delta Special Forces guy - but my own aiming is badly influenced by game factors, the accuracy of the guns are crap and I'm not able to stop breathing if I snipe (Ive to use max. strength for a little compensation). Using the silencer makes the weapons laughable weak, distant attacks lead to some kind of slapstik comedy. You can't kill the enemies as long as you don't hit their heads but they aren't able to figure out where the bullets come from either, showing a - uhm - "not very smart" behaviour. "Benny Hill Show" anyone?

Actually I could accept this - if the A.I. wouldn't hit me like crazy inmidst the jungle with all its bushes and tress and shadows while running in 100 feet distance. Its "funny" - in no other game I have so much trubble to hit the damn head while it feels like the A.I. hits yours all the time in any situation. - A.I. on boats and in copters makes it even more unfair. I just skip this special case ...

4. The enemies in the area concentrate themself way to much at the very same position after a short fight you escaped cloaked. Sometimes they do it so hard that some of them get literally squashed to death. And to often they just stay there forever, "keep looking" every square feet again and again until the end of time. Perhaps the "Yankee Shankee" may show up some time - if they stare long enough at his last position. That a single grenade could kill them all at once is not their concern - they're Pros. They know it better, they watched one episode of "A Team". The very same episode 3 years long. And they're fans of Colonel Lynch. That's why they're Pros.

5. Obvious bugs. Try it yourself: headshot some one in the far distance (with silencer and sniper scope) and you may notice that some other enemy nearby instantly runs ahead to your position. This happens especially on "relic" (perhaps only - I didnt doublecheck it). I could observe this several times and can repeat it whenever I like to. Ive noticed this very late - and wasn't surprised anymore where the hell they came from after I made pretty sure nobody is behind me.
Copters seem always linked to my position, one or another shooting rockets at me even though the gunner "Callsign Eagle Eye" isn't firing. They also use infrared or something because trees don't trubble them much. Good to know that my cloak device even hides any heat signature ...

Okay, a lot of text and complains. I must repeat - the A.I. felt okay the first time I played the game. But after a few more rounds it indeed felt pretty artificial and I DO believe it could be better nowadays at least a bit more balanced. Crysis has awsome next-gen graphics - I'm still impressed every time I start this game. But when it comes to the A.I. its not next-gen very much.

Better overall balance and a bit more CPU time for the A.I. could have been a good idea. I guess Crytek was to much concerned about CPU usage - but if I look at the average CPU usage there is plenty of space left, my graphics card seems far more the limiting factor. (E6750/8800GT)
