I love it so much.

And yeah... try playing the Sniper Levels on Regular or more... the end of that level was INSANE, just unlimited dudes, and on the harder settings you just die faster and it's so hard to kill everyone.

From then on I've been struggling a bit, the level where you've got to go up the hill and defend at each step of the way and then get back down the other way was also insane...

I'm hoping there are more middle eastern levels fighting in the streets they are so impressive as the US fighters, love that shit... haven't started ACT III yet. They really do a good job of making you hate the enemies as well.

This game kicks Metroid 3's arse... I honestly don't even know if i'm going to finish Metroid - it just came out in AUS as well and I can't seem to pull myself away from COD4 multi...

This is my GOTY so far for me... I'm not sure if Mario Galaxy will be able to surpass it... There isn't anything else better than this for me.

 I breezed through the TV station, didn't die once... I flanked the bad dudes in a room and just cained them.

The Russian Missile station has been hard as fuck so far, they just keep bringing in more dudes on helicopters... funny as fuk when u fire a grenade into the back of the chopper and 20 dudes fall out all dead though :D

I haven't had a chance to play it online because apparently the PS3 (and PC too?) suffers from online problems that I guess the 360 had gotten fixed in the multiplayer beta, but the singleplayer is good.

The story is good, but not amazing. I do wish that the entire game was not only longer, but I think they could have done more with some of the missions. I liked the American missions in the Middle East a lot because it was a massive firefights and the environment and feel of the levels were very intense. However, there weren't enough missions and you soon find the Middle East campaign over (wont spoil the story). The SAS missions felt too covert op for me. At least for most of them (with last missions of the game being the exception) because I like the large scale battle feeling that Infinity Ward puts out compared to other war games. Despite that, the last levels and the ending were pretty cool and intense.

I've tried the demo on my PC and I was able to have it look fairly well without my FPS being too low, but I think a new video card is in order as I'm covered in other areas with my recent upgrade to other parts. This game is awesome on the PS3. It not only looks great, but it's also smooth as silk when it comes to the frame rates and I could notice a small drop in frame rates at a couple of points in the game, but that was a small drop and pretty rare (kind of like Resistance: Fall of man, smooth as butter and fast paced).

The gameplay is good and it feels well balanced. The enemies take cover more than in COD2, but the material mechanic is a neat feature by letting you shoot through walls or objects to hit your target. The sound is just as good and turning up our 5.1 surround sound engulfed the room in battle, which was awesome.

Apart from the length of the game and the shortness of the Middle Eastern campaign, the other complain (somewhat) I have is how much it resembles COD2. Obviously it's not a negative, but it almost feels like COD2 with better graphics and better scripted scenes, but whatever it's still awesome.

Love it!

 Oh my god, the Sniper missions on regular was pretty rough. It took me a great number of tries to get through it (probably less if I was playing it on a keyboard and mouse as opposed to a controller on a console). 

As for your other post with the spoiler censor. . . Yea, that area is pretty rough too.  

this game is kick ass! i like the death from above mission, easy but fun

I didn't dislike it, but I wasn't impressed at all. My complaints:

We beat the main campaign in 4 hours. There was another mission after it to unlock arcade mode, but it wasn't very fun and neither is arcade mode. There is no co-op. Lack of a cover system or any squad commands in a military style FPS is inexcusable. The gameplay is nearly identical to CoD2. For some reason my enemies and my allies can duck behind cover and open doors but I'm not allowed to. I guess my character has down syndrome. Also, the levels are too linear to allow for any tactics such as flanking.

The enemy AI is just screwed up. First of all, the AI is apparently made up of Peyton Manning and Tom Brady clones because they can drop a grenade between your shoes from 100 yards out. The grenade indicator blows, so you never notice it until too late. Second, they often charge at you like bulls. I understand that good AI is difficult, but seriously, at least don't have them run at you head on.

The multiplayer was definitely the strongest part, but there are only 6 game types, and no CTF. No vehicles really sucks. Again, it's a war-style FPS and it's supposed to have a squad feel. No vehicles really detracts from this.

Well, with the bad out of the way:

The class and perks system is pretty awesome. It has some great customization options, and it's a really creative addition to the multi-player. There are a solid 16 multiplayer maps, although about half of them suck. The game has the best graphics of the generation to this point, and is the closes to photo-realistic any FPS game has come.

Overall - it's a solid FPS, but it's missing a lot of features it should have, and despite the gorgeous graphics, it really feels too much like Call of Duty 2. Both my friend and I agreed though that it was a good thing we rented it instead of bought it.

 I went through the TV station no problems =P

Seriously though, are you playing on veteran?  Because the end of that sniper mission on veteran mode is easily the mission I have heard the most gripes about as far as difficulty. 

Just wondering...

Why would you expect to be able to issue squad commands in campaign when you're not of proper rank to do so?

 because it is fun?  

Being serious though, I think the point being made was that the NPC squadmates can get in the way some time and it would have been nice to be able to interact with your men more. If that meant your character was a higher rank it really wouldn't have been much of an issue from a development standpoint to make you a higher rank....the squad commands themselves might have been an issue.
