What kind of infection is going on in the story? I'm new to Crysis and I played the Xbox Demo. I saw the Story Trailer and heard there was an infection and places were quarantined.. Are they turning into aliens, zombies, what?

It looks like I have around 40 views but no one can answer to this?

In the latest trailer the offscreen voice mentions it being used as an area-denial weapon. This is my best guess, the Ceph know human biology, and have developed a virus to kill us off enmasse, at least in NYC. Maybe theres something under manhattan, or maybe they're just testing it before going after the rest of humanity.

But in the Story Trailer one of the infected victims states, "its moving inside of me." like something will come out or he is just turnining into it...

Instead of asking here for spoilers, why dont you do the sensible thing and wait till the games out and be immersed in the story. Instead of having it told to you first and ruining the experience.

It's possible they're using the virus (or whatever) as a means of doing something, though whether they'er using humans as incubators (for whatever), or altering human dna I'm not sure. If they're using humans as incubators, the quarantine would be a lot less effective, I.E. human gets infected, things pop out (killing the human) and go on to infect other humans etc. If they're altering human dna, they may be trying to make humans more like them, the easier to control us. Or they may be using humans as a means of altering their own dna, creating a virus that results in a ceph thats adapted to earth's environment, probably popping out of a human.

Keep in mind, I'm probably missing something, but those seem like definite possibilities to me.

@ lexandro - at this point its all speculation, I personally enjoy trying to figure some of these things out.

if you watch the story video it shows the virus started before the aliens showed up.
im not saying that it isnt caused by the aliens just saying it was around slightly before the invasion my theory is that the aliens are softening up the human race to make the invasion easier.

Alright, just rewatched the trailer, the quote from the infected guy in the subway tunnel was "its eating me" and later the voiceover said "They wipe us out, they break us down" bout 15 seconds later another disembodied voice says "You're looking at an area-denial bioweapon beyond your wildest dreams". So it seems that the virus was created to be a complete extinction-causing weapon for use against humanity.
