This review is meant for people who already own and are familiar with the game and for it's developers.
After playing through the campaign and up to lvl 28 in Multiplayer, I am done (for now) with Crysis 2. Here's why:

Graphics: 8 / 10
wonderful detail. Nothing is lacking in art and complexity. The frame rate is, unfortunately, wanting. The low frame rate causes some aweful situations in Multiplayer. (like enemies appearing out of nowhere because the frame rate didn't show them falling in front of you, or worse, disappearing because the frame rate didn't keep up with him cloaking)

Mechanics: 8/10.
But Wait! This should be 10 out of 10 but there were some awful decisions made when it comes to brass tacks in Multiplayer. For example, back hits DO NOT kill enemies. This is not a problem because they do in Halo. I feel Halo is stagnant and boring. It is a problem because Stealth kills are GLITCHY and UNPREDICTABLE. Result: Good players don't use the mechanic AT ALL because if the stealth kill glitches, you drop your power level to zero and just punch the guy in the back. If he doesn't svck, and he is not lagging, he has time to turn and kill you. I cannot imagine why this mechanic was left this way unless playtesting didn''t reveal the instability of the stealth kills. Also. In my opinion cloaked enemies should die IMMEDIATELY when hit. This would cause people to be a bit more cautious and reward players for spotting cloaked enemies rather than spray, pray and hope the cloak drops.

Story: 5/10.

A bland affair. Nonsensical and silly. No worse than most shooters though. Just listen to the recap: Honeboy finds out that aliens are coming so he designs a suit for people to be able to fight back. The suit gains pseudo sentience and becomes symbiotic. It copies it's owner's personality and, through a long and ambiguous chain of events, gains the ability to make the Alien's bio weapon kill them instead of us.......
Dumb.

Sound Design: 2 / 10.

Maybe it's my Turtle Beach headset... This game, from the ground up, has the worst sound among it's big title competitors and by a LOT. Not only are there not enough variations in sound (a guy next to you sounds the same as he does through a wall for example - inexcusable) but the game is plagued by pervasive sound glitches. I am not exaggerating when I say that there is almost ALWAYS a sound glitch happening at any given moment. From ghosts choking to death to ten marines screaming in your ear simultaneously.
Add to this that the sound levels cannot be adjusted, which caused me ( and many others from what I can gather ) to disable the music entirely because it's bass was too deep for my speakers causing ridiculous distortion.
Also also: the Marines in campaign have a direct line to your ear. This is realistic but it means that they are all screaming in your ear AND when someone says "this way idiot!" into your headset it's not you who's being an idiot it's the guy (and the sound designer) who said it - because you can't tell where the sound is coming from.
Finally, but not least, it seems that someone thought it would be a good idea to make all the invisible characters that talk to you in Multiplayer @$$holes. When I lose an incredibly frustrating match because of unprecedented latency issues (as we will go over in a moment ) I do not want some woman I have never met telling ME that I svck. Nor do I want some moronic marine to say "f you a hole" when his controller kills me. Unless you are TRYING to FOSTER the kind of idiotic smack talking culture that Halo has managed to cultivate, these decisions are impressively bad. ALSO ALSO ALSO you can't turn that crap off. Please note that swearing itself doesn't bother me at all. What bothers me is getting screwed and then getting made fun of for getting screwed by the people who screwed me. Not funny. Not cute. Not okay. It makes me want my money back.
With these points in mind I'm specifically calling for the sound design head's head (his job) and would like to hear seconds from other gamers who feel the same. I'd of course be content to hear whose fault it actually is if not the director's.

Multiplayer: 6/10

Please note that everything is great EXCEPT the following issues which make the experience FRUSTRATING.

1. Kill cams show total BS 90% of the time. They show no hit, the gun doesn't vibrate, people are glitching around, bullets traveling in slow motion through seven feet of concrete.... if you can think of something you don't want to see in a game, the kill cams show it to you. It's almost as if the game invents the crap out of thin air. Most matches end with everyone laughing at the silly final kill cam. What a waste of space. PLEASE RELEASE A PATCH THAT ENTIRELY ELIMINATES KILL CAMS or ( I doubt it ) fix them. They are currently a laughing stock.
2. Latency. Latency. Latency. Numbers will soon make this more clear... I have never played a game in which host had such a retarded advantage. When I host my K/D quadruples. When not connecting, you can dump dozens and dozens of bullets into enemies to no effect. I understand that all games without servers suffer this problem but: this game is the worst about it AND doesn't that mean it should get servers?!?!? This issue WILL kill this game dead if not addressed.
For some reason the demo worked eons better for me than the final product.
3. Every time it migrates hosts it boots everyone. Already, the lobby empties when the host tries to migrate.
4. About 40% of the time you search for a game you start alone in the lobby, have to back out and re-enter. A joke.
5. About half the games I join dissolve before round 2. I don't know if they are rage-quitting or what but this is annoying.

In short: The multiplayer is amazing BUT you spend about 80% of you time dealing with BS for those awesome ten minutes. Ultimately it's not worth the frustration. If these issues get resolved and you bring it down to like 30% wasted time, we may be looking at the best multiplayer ever. I've taken the time to write this because I truly feel that 95% of the work is done and is great and it would take so little for this game to be the next big thing.

So there it is, I'd love to hear back from the developers about weather any of these issues are being dealt with. I'd love to own a gem here, but for now it's a bit of a dud after the campaign ends. Poop.

MP comments slightly justified but sound complaints....seriously? Do you hear how the sound of your rounds being fired echoes around the city? It's pure art and beauty. I have only had one sound glitch with one and a halfway throughs and that was some scripted voice overlap. Otherwise I think the only game with sound that could maybe match this would be BFBC2.

"Homeboy" needs to ditch the Turtle Beachs. This game's sound is great on stock TV speakers, can't imagine a full surround sound!

yes the sound shines, but it also can sound like a badly mixed, clipped up dubstep song.

I really do enjoy this game despite quite a few minor issues, but something reminds me of IW.

What about the ghosts dying and in a deserted street you can hear pandemoneum from half a mile away? I hear that stuff too. I agree that the sound designer screwed up some things that were obviously overlooked by the developers. And that bich at the end is really annoying, but after losing a bunch I ignore her.

And yeah, hosts seem to migrate more late at night EST. I got the medal for playing after 2am at 6:30 pm today, so maybe Crysis runs on German time?

there are a few glitches

1 where they talk voer each other
2 Static sound which wont stop unless i reload chapter

But i only had that problem like once or twice, weapons sound good but the ally/enemy location sound this was a waste as all i could hear was my ally clinking sound which pissed me off.

I have had a few times where the kill cam will show me being shot at, but since it doesn't show the bullet actually go into the body, the bullet will go into a wall then the kill cam will end. Just like saying "alright we are showing the killcam, oh **** it we know this kill was bs but oh well."

To the guy who said this game has the best sound other than BFBC2:
We must be playing different games. Flat out.
As for echoes.,.,They are the ONLY ambient effect being layered on. When you spawn into a Multiplayer map close your eyes and you will see that the gunfire sounds like the same effect layered over itself ten times. Go into ANY other major title and you don't have the same experience.
It could be my headset, but this would be the only game that doesn't sound BETTER through them than my other speakers.
I suspect the opposite is actually true: that I am hearing problems that you are not because my sound is BETTER.
I've heard similar complaints from other gamers who use higher end head-wear.
Also also, the guy choking to death is not cool ambient noise meant to deepen the feel of being in a recently destroyed city, it is a repeating and annoying glitch. To make matters worse, the repeating sound file is the same one used when players get shot in the throat (recycling sound bits is a pervasive problem), so I'm constantly running over to see who died and claim the victor only to find out that the area is deserted and corpse free. I'm not the only person hearing it, about 2 people in every lobby I'm in also hear it. My guess is that they are the ones with good sound systems.
If you're listening to your game through the stock TV speakers then all games will sound equally crappy. It is no surprise that you don't think the sound is crap because you can't hear the better sounds in other games.
Please understand that I am not an audiophile, I don't normally care a fig about sound. I've simply found that in this game there is almost always some annoying sound going on and the general direction with the voices was terrible and annoying.
In that vein, I'm not trying to assert that all is lost because of bad sound. Far from it. I can put up with bad sound just fine if the multiplayer stuff gets resolved.
