Seriously.
 
One of my favorite parts of the first Dead Space was when Isaac swings his weapon or boot stomped. The voice actor captured a perfect desperate-frightened cry as if he was shouting at the Necromorph 'JUSTSTAYTHEFUCKAWAYFROMME!'. I thought it was pretty realistic and was wondering; is that kinda stuff and the general desperation of Isaac captured well in this sequel - or is it more, shall we say, hollywood(?!) this time?

I think it has a bit of both.  At the start of his stomping spree it is the sounds of a desperate man.  Then near the end of it he may shout the word "fuckers" or something similar, adding a sweet end to the experience.  You can do it again and again.

fucker? NO. he won't say it in the game. it's only happened during cutscenes.

It seems his sweet shouts are intact.  I love stomping and swinging over and over for no reason.  Sounds so good on my surround sound.

Oh yeah. The Viking Roars is what I always came 'em. <3

" fucker? NO. he won't say it in the game. it's only happened during cutscenes. "

How long til we see youtube remixes of Isaac Clarke singing his hit single 'Fucker!'?
 
Only time will tell.....

I distinctly remember stomping a necromorph about 10 times and at the end it sounded like a veeeery light "mother" then FUCKER.

I love it, it's a great detail. It's what you, as the player, is feeling as well.
