After weeks of anticipation, replaying the original Dead Space, and sitting through about 4 of those God awful minigames in Ignition I finally started playing Dead Space 2 last night. This, to my horror and shame, ended very early on as I got stuck in the first chapter. 
 
I am in the Triage Room with the stasis beds before even collecting Isaac's proper armor. This room has both the Hacking and Stasis tutorials in it. After hacking a computer terminal in the Triage Room a large Necromorph falls from the ceiling into a malfunctioning stasis unit. This necoromorph has killed me dozens of times, forcing me to continually suffer both the Hacking segment and the inevitable death. I have shot this thing in the neck, arm and hip joints repeatedly but every time it kills me in one hit. I have full health upon entering this room. I have only succeeded in getting behind the necromorph once, but by then it has exited stasis, turns around and immediately kills me. 
 
What is most upsetting is the amount of time Isaac takes getting out of his Hacking animation. As I watch the monster run towards me, barreling ever closer, Isaac slowly and methodically removes his hand from the computer, grips his hand and then, after the beast is right on him, I receive control of Isaac. Am I missing something? 
 
Any help would be greatly appreciated as this room is completely preventing my continued enjoyment of the game. Thanks.

Use more skill.

Stasis him then shoot? As long as you don't miss he should die fairly quickly.

Stasis the monster IMMEDIATELY. I had the same issue initially, but you should have time if you complete the hacking fast enough.

Shoot it with stasis the instant it gets out of the first stasis. I died here a couple times too.

You got stuck at this?! Really?

Good luck have batman.

" You got stuck at this?! Really? "

" Good luck have batman. "

hit it with stasis right away, shoot, then stasis it again, then shoot. 
 
I had trouble with this part, too.  

its a rather stupid design decision by the devs...I don't blame you.  The necromorph is invincible unless you stasis.  So ignore the couple of jackasses that are mocking you here.

I died to it the first time to see if it was any different to a normal 'morph, it was, then I thought oh stasis, boom dead. 
 
Hardly being elitist, just didn't understand people were getting stuck at what to me, was a trivial part of the game.

I hit it with stasis as soon as I saw it, since I just got stasis and was eager to use it. Do use some stasis.

Oh yeah thats the monster that one hit kills you. 
 
Stasis is the key my friend.

aim at necromorph, press Y button, shoot. done.

Stasis it immediately.

I died about 5 times at this part before I got it. Kind of stupid they would ask you to stasis him after he was in stasis, but whatever! 

Yup, you definitely have to hit it with stasis immediately and then pop a cap. What's funny is that I beat the game already and had no problem with that part the first time. Last night I started a game on Zealot and died over and over right there before figuring it out. I think the fact that the necromorph is in stasis before you do anything is what messes people up.

Woah, really?  I understand they are trying to teach you how to stasis, but making it invincible unless you do the thing they want you to is... kinda jerky considering the situation. "

ya...it killed me 2 times before I realized I couldn't hurt it until I used stasis.  The problem is that the necromorph suddenly falls out of the ceiling and gets stasised automatically....so why would you want to stasis something that is already stasised?  And second, it's like it makes you learn under fire....you have a necromorph charging at you and a little turtorial pops up ingame next to Isaac that you can barely read that tells you how to use your stasis (yes I have an HD TV).  So I found it pretty stupid as well that you couldn't hurt it without using stasis.  I'm not sure if it is just Zealot but it also kills you in one hit. "

Yeah it was stupid of them to show the monster in stasis. It makes you think the game's giving you plenty of time to line up your shot, when really, you're supposed to stasis it first.

" @Ygg:  You're amazing. "

I got rofflestomped so hard here...   I never played Dead Space 1..  Watched a "let's play" of it to get the story, jumped into this one..  I start up.. die in the first area when your running away.. "wow.. I thought this was normal difficulty..."   Run through there..  felt kind lame for getting smoked in the tutorial.. then.. this bit..   this was deaths two and three.. So not nice when you get one shot trying to figure out what to do in a panic.  >.<   Got through it by finally getting stasis off as it's on top of me and SPAMMING SHOTS AMG I'M GUNNA DI... oh.. it's dead... I WIN!

There's a few things you can do.  If the monster is coming during the hacking mini-game you can cut the mini-game short by pressing B (I don't know the button to press on the PS3 version).  Like others said, you can stasis him.  Take out his legs before you take anything else out.  This will give you more time to move.
 
Also, you can turn down the difficulty.  You don't get any difficulty achievements/trophies unless you are on the level above survivalist. 
 
EDIT:  Oops, I didn't see the other post.  Uh...use stasis!

you should be ashamed...oh wait, you are.  Good day!

Whoa wait that Necromorph can one hit kill you? I didn't know that because I hit that fool with stasis when it said hit Y to use stasis and shot him. With that said though that is pretty poor design because if I remember right that Necromorph runs through a stasis field also and I can see how you wouldn't even worry about using stasis at all on that part.

I'm not adding anything to this thread but you should use stasis.
