I just finished the campaign and I got 2 say....I'm rly disappointed. Compared to CoD etc etc this is quite a good singleplayer. Compared to Crysis this is complete ****. In Crysis there were so many ways to kill/attack e.g. a korean camp so I could play through it 7 times without getting bored. In Crysis 2 you havent got very much opportunitys. Also you have a far too narrow gameplay-area.
The story sometimes seems to be totally different from Crysis and sometimes totally weird (The suit e.g. improves in the video-sequences over and over again...but I didnt notice any change ingame). Aliens and their technology is now shiny red instead of blue. They now have some kinda helicopters instead of flying around in that kraken-like thingys. <.<
Why ain't Alcatraz sayin ANYTHING? Thats just stupid...he gets asked stuff a lot and he just doesnt answer...and the person asking that question just keeps on talking then...
But the worst thing are the missing (what I call it) Crysis-moments. I had like...3. First one when the walker-thingy which you barly see does its shockwave behind the glass in the water and you get washed away. Second one when the walker-thingy breaks through the wall to that hall. Third (and best) one when central-park gets elevated into the sky. In Crysis there were much more....like everything which happened on the aircraft carrier just to name a few. This atmosphere was unique and I rly hoped you could continue that with Crysis 2 cause Crysis was the best Shooter-Singleplayer I've ever played....but I guess you failed...and I find that very sad cause I was so looking forward to it

Conclusion:
The campaign is not bad...but not better than some CoD campaign or such...and far behind Crysis'.
Consoleros wont ever experience the REAL Crysis-feeling
